The invention relates to a power output operating device for a tractor. The power output operating device comprises an operating lever, a connecting arm, a pull rod, a rocker arm and a push pin, wherein the operating lever is integrally fixed with the connecting arm through a hinge joint seat; and the push pin extends into a rear axle transmission case. The power output operating device is characterized in that one end of the rocker arm which is arranged horizontally is non-rotationally connected with the push pin; the push rod is in vertical hinge joint between the connecting arm and the other end of the rocker arm; a rectangular hole is formed on a seat plate; a jointed shaft stretches over the rectangular hole, and the two ends of the jointed shaft are fixed together with the seat plate; the operating lever is hinged with the jointed shaft through the hinge joint seat; a pressure plate for shielding the rectangular hole is fixed on the seat plate, and is provided with a hinge joint seat hole; the size of the hinge joint seat hole is slightly larger than the physical dimension of the hinge joint seat; and the hinge joint seat penetrates through the hinge joint seat hole. The operating lever is hinged on the seat plate on the side edge of a driver seat, so that the leg accommodating space in a cab is large, and people can get on / off conveniently; a driver can operate the operating lever conveniently in a labor-saving way; and the rectangular hole is shielded by using the pressure plate, so that the leak tightness of the cab is high.

The invention discloses an accessory tool rapid locking device and a locking method. The accessory tool rapid locking device comprises a locking clamping part, a driving conduction part and a supporting part, wherein the driving conduction part comprises a lower pressing plate and an upper pressing plate, and one end of the upper pressing plate is connected to the supporting part; the locking clamping part is arranged in the supporting part and extends into the upper pressing plate; when the auxiliary tool is installed between the lower pressing plate and the upper pressing plate, the locking clamping part drives the lower pressing plate and the upper pressing plate to clamp the auxiliary tool, and the lower pressing plate and the upper pressing plate are connected through a shape locking structure capable of transmitting torque. A first protrusion matched with the accessory tool installation hole is arranged at one end of the lower pressing plate, and when an accessory tool is installed between the lower pressing plate and the upper pressing plate, the first protrusion is inserted into the accessory tool installation hole. Torque can be transmitted through shearing force, so that the required clamping force is small, and the operation of the rapid clamping operation part is more labor-saving. Locking and loosening can be achieved without the help of additional tools, and the device can be matched with various auxiliary tools in the prior art.

The invention discloses an automatic clutch which comprises a driving disc, a driven disc, swing arms and a friction element. The driving disc is provided with at least two swing arms in central symmetry. Each swing arm is respectively provided with a fixed end and a swing end. Each fixed end is respectively connected with the driving disc directly. Each swing end is respectively connected with the driving disc by a spring. One end of the friction element is connected with the driving disc in a fixed way, and the other end is connected with the swing end of the swing arm or the position near the swing end by passing around the driven disc. The shrink moment of the spring is larger than or equal to the centrifugal moment of the swing end of the swing arm when the driving disc rotates at idle speed. The automatic clutch achieves the technical effect that the driving disc and the driven disc are separated thoroughly and are jointed mildly under the condition of ensuring the dynamic-static balance of the clutch. The automatic clutch works stably, has simple structure and low cost, has low vibration and noise at work, saves labor for operating, is convenient for maintaining and is favorable for popularizing and applying.

The invention relates to a steering system for a five-axle heavy duty car. The forward-rotation output shaft of a right angle gear box is connected with the input end of a front steering gear through the transmission shaft of a first front axle, the output end of the front steering gear is hinged with the middle part of a driving arm, the lower end of the driving arm is connected with a steering arm on a first wheel hub through the longitudinal tie of a first front axle, the upper end of the driving arm is connected with the upper end of an oscillating arm through the upper tie rod of a second front axle, the middle part of the oscillating arm is hinged on a longitudinal beam, and the lower end of the oscillating arm is connected with a steering arm on a second wheel hub through the longitudinal tie of a second front axle; after being decelerated, the backward-rotation output shaft of the right angle gear box is connected with the input end of a rear steering gear through a transmission shaft mechanism, and the output end of the rear steering gear is connected with a steering arm on a fifth wheel hub through the longitudinal tie of a fifth axle. The transmission part of the steering system is under very small stress, the flexibility and the reliability of steering can be guaranteed, the operation is labor saving, and the steering system has the advantages of simple structure, easy assembly, light overall weight, low consumption of materials and low production cost.

A reverse unit installed to the secondary shaft of speed variator for motor-cycle is disclosed. A shift for assembly sleeves on a slide axle. Its fork is connected to cynchronizing ring engaged with the drive teeth of splined sleeve. The reverse gear and output toothed sleeve respectively sleeve on the splined sleeve at both sides of its drive teeth. The reverse gear is engaged with a connecting gear A. The output toothed sleeve is engaged with another connecting gear B. A is locally engaged with B. The splined sleeve is linked to the spline of said secondary shaft of speed variator.

A floor-standing brake master cylinder performance test device, including an air source system, a fixed base, an adjustable support and a pressure rod mechanism, the adjustable support is arranged on the fixed base, and the adjustable support is equipped with a brake master cylinder. The pressure rod mechanism can be rotatably installed on the top surface of the fixed base. The center of its rotating shaft overlaps with the center of the pedal rotating shaft of the master cylinder.
