The invention discloses an automobile maintenance bracket, the structure of which comprises: a new type limiting device, a movable plate, a main bracket, a lifting rod, a hydraulic roof, a support plate, a fixed bottom plate, an electric box, a mounting seat, a sliding plate, a baffle, a connection Plate, strong spring, limiting plate, the sliding plate is located on the outer side of the connecting plate and is an integrated structure with the connecting plate, the baffle is located on the upper surface of the sliding plate and is fixedly connected with the sliding plate, and the limiting plate is located on the upper surface of the connecting plate The right side is movably connected by loose-leaf, the strong spring is located on the upper surface of the connecting plate and is fixedly connected with the connecting plate, and the sliding plate is movably connected with the main bracket. The maintenance bracket can prevent the car from slipping backward during the maintenance process, so that the personal safety of the maintenance personnel will not be threatened.

A slippage preventing system for vehicular hill starting is mounted on an axle of driven wheels by a one-way brake starter through a support. The one-way brake starter comprises a ratchet wheel, a flywheel in a pawl structure or a ratchet-gear wheel in a shell, a rack push rod meshed with the flywheel in a pawl structure or the ratchet-gear wheel and a return spring on the rack push rod and a truckle, mounted on a same shaft with the flywheel or the ratchet-gear wheel, outside the shell. The slippage preventing system is controlled by a hydraulic passage or an inhaul cable connected with the same and disposed in a cab. During hill starting, the truckle is combined with a rim part of a brake disk or a hub, when slippage occurs, the rotating rim of the brake disk or the hub drives the truckle outside the shell and the flywheel or the ratchet-gear wheel in the shell to poke the rack push rod outwardly so as to compress an auxiliary brake pump piston at the position, braking is achieved by the aid of the hydraulic passage connected with the auxiliary brake pump and a driven wheel brake caliper or an auxiliary brake caliper, and braking stops when a vehicle advances.

The invention relates to the technical field of automobile braking, in particular to a vehicle driving safety control system. The system comprises a controller, a hill-start backward sliding prevention control system, a driving emergency brake control system, a reverse tooth gear shaft sleeving an automobile transmission shaft and reverse teeth on the reverse tooth gear shaft, wherein the hill-start backward sliding prevention control system comprises a backward sliding prevention switch, a first-gear switch, a gradient sensor and a backward sliding prevention electromagnetic valve; when the condition is met, the controller electrifies the electromagnetic valve, armature pusher rods moves downwards to press a lock rod to press against the reverse teeth and prevent the transmission shaft from rotating anticlockwise; the driving emergency brake control system comprises a pedal position sensor, a pusher rod extreme position switch, a reverse switch, a wheel speed sensor and an emergency brake electromagnetic valve; during electrification under the condition, the two armature pusher rods press the reverse teeth from the two sides to prevent the transmission shaft from rotating clockwise and anticlockwise. The vehicle driving safety control system has functions of prevention of a vehicle from sliding backwards and automatic emergency braking, so that the safety of the vehicle can be improved, and vehicle accidents are effectively avoided.

The invention relates to a roller-shaft-type car intelligent uphill and downhill auxiliary apparatus. The roller-shaft-type car intelligent uphill and downhill auxiliary apparatus comprises a roller shaft apparatus, a damping wheel, a position and speed detection apparatus, a solar panel, a power generator apparatus, a storage battery, an LCD display screen and a controller module, wherein the roller shaft apparatus, the damping wheel, the position and speed detection apparatus, the solar panel, the power generator apparatus, the storage battery and the LCD display screen are connected with the controller module, when a vehicle passes by an uphill pavement, the roller shaft provides the forwarding power to the vehicle by virtue of rotation, and an effect for preventing the backward slippage of the vehicle can be realized; and when the vehicle passes by a side-by-side roller shaft apparatus of a downhill pavement, the position and speed information of the vehicle at the moment can be detected by virtue of the position and speed detection apparatus, the controller displays the speed on the LCD display screen, the greater the vehicle speed is, the greater the damping of the damping wheel on the roller shaft apparatus is, if the vehicle speed is greater than a given threshold value, the structural design is simple, the auxiliary apparatus is more effective than the ordinary uphilland downhill auxiliary apparatus, and the action effect is better.
