Problems solved by technology

This kind of spherical slideway structure is very flexible when braking, which is a major advantage of this patent. However, this flexibility is not an advantage for the parking brake of the loader. In order to prevent the accidental sliding of the steel ball in the slideway, the patent sets The brake is added, which makes the structure complex. In addition, the processing of the spherical slideway on the joint surface of the drive shaft and the caliper is relatively difficult, which makes the cost higher

Embodiment Construction

[0005] In order to facilitate processing, the overall structure of the pliers body is changed into a split structure in which the cover plate 3 and the pressure plate 2 are connected by screws. In order to improve the reliability of braking, the present invention changes the three spherical slides evenly distributed on the end face of the drive shaft 1 into three trapezoidal spiral ramp convex bodies evenly distributed along the circumference, and the trapezoidal spiral ramp convex body consists of It consists of two spiral ramps 5 and a plane 6 between them. Since the axial gap between the brake pads is generally about 1 mm, the height of the ramp convex body does not exceed 2 mm, and the length of the two ramps should be greater than the length of the plane. , and the end surface of the pressure plate 2 combined with the drive shaft is also provided with a trapezoidal ramp convex body engaged with the trapezoidal spiral ramp convex body on the end surface of the drive shaft. ...

Abstract

The invention discloses a shut-down manual brake, which relates to a brake device, and the invention aims at providing a manual brake with reliable performance of shut-down and braking and good manufacturability. The invention has the technical proposal that the shut-down manual brake comprises a drive shaft and a transmission mechanism among conjunctions combined with the drive shaft, and spiral ramp convex bodies are uniformly distributed on the end face of the drive shaft along a circle; spiral ramp convex bodies which are meshed with the spiral ramp convex bodies on the end face of the drive shaft are uniformly distributed on the end face of the conjunction along the circle, and the end face of the conjunction is opposite to the end face the drive shaft. The invention is used for engineering machinery.

Description

Technical field: [0001] The invention relates to a brake device, in particular to a parking manual brake used for large construction and engineering vehicle equipment. Background technique: [0002] The hand brake is a braking device when the loader is stopped and stationary, commonly known as the hand brake. Loaders often work in the field, and the road surface will be inclined when parking. In order to prevent safety accidents caused by the vehicle moving by itself, the reliability of the hand brake of the loader is required to be higher. The U.S. Patent No. 5.529.150 discloses a parking brake device. The purpose of this patent is to solve the problem that the structure of the existing brake device is very large and expensive and the environment corrodes the transmission mechanism. The structure of the brake brake of this patent is composed of a Composed of U-shaped calipers, rotors, brake discs, handles, etc., three spherical sliding ramps with constant angles are evenly...
