Abstract

The utility model relates to a parking brake which can effectively solve the problems of complicate structure, large volume, ponderosity, troubles in use and high energy consumption amount of a conventional electric car parking brake. In order to solve the problems, the parking brake adopts the technical scheme that the parking brake comprises a clamp body, a pull rod and shaft pins, wherein the rotating pull rod is arranged on one side of the clamp body, and a bracket is arranged on the other side of the clamp body; shaft pin holes are formed on the clamp body; the shaft pins suspended on the bracket are mounted in the shaft pin holes; a spring is arranged at one end of each shaft pin, which extends out of the clamp body and is in contact with the pull rod, and the other end of the shaft pin is in contact with a braking block group mounted on the clamp body; and the lower part of the clamp is mounted on a clamp rack. The parking brake provided by the utility model has the advantages of simple structure, convenience in use and light weight, and is an innovation on parking brakes.

Description

Parking Brake

One, technical field

The utility model relates to auto parts and components, particularly a kind of Parking Brake.

Two, background technology

Automobile is the best transportation means that we go on a journey; light and fast; it is the symbol of human civilization; along with energy shock is increasing; electrocar gasoline replacing car is the certainty of social development; to reach low-carbon environment-friendly; the purpose of energy savings; Parking Brake; claim parking brake again; employed drg is moved in slide before and after preventing vehicle after stopping exactly; Parking Brake on the present electrocar is generally traditional drum brake mechanism and piston overhead type drg; owing to its structural reason, cause present Parking Brake to have the structure trouble; problems such as the big and heaviness of volume, troublesome poeration during use; energy-output ratio is big, so electrocar brake system upgrading is had very wide significance.

Three, summary of the invention

At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of Parking Brake, can effectively solve existing electrocar vehicle stop brake mechanism trouble, volume is big, heavy and use bothers and the energy-intensive problem, the technical scheme of its solution is, comprise caliper, pull bar and pivot pin, caliper one side has the pull bar of rotation, opposite side has support, pin hole is arranged on the caliper, the pivot pin that is suspended on the support is housed in the pin hole, stretching out on the end of pivot pin of caliper has spring, and contact with pull bar, the other end contacts with slipper group on being contained in caliper, and the caliper bottom is contained on the tong holder, and the utility model is simple in structure, easy to use, in light weight, be the innovation on the Parking Brake.

Four, description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is a section right elevation of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Provide by Fig. 1 to Fig. 2, the utility model comprises caliper, pull bar and pivot pin, caliper 5 one sides have the pull bar 7 of rotation, opposite side has support 4, and pin hole 11 is arranged on the caliper 5, and the pivot pin 9 that is suspended on the support 4 is housed in the pin hole 11, stretch out on the end of pivot pin 4 of caliper 5 spring 10 is arranged, and contact with pull bar 7, the other end contacts with slipper group on being contained in caliper 5, and caliper 5 bottoms are contained on the tong holder 3.

In order to guarantee result of use, on the said caliper 5 bearing 8 is arranged, pull bar 7 is rotary and is fixed on the bearing 8.

Said pin hole 11 has two, is symmetrically placed in the left and right sides of caliper 5.

Said slipper group is made of the first slipper 6-1 and the second slipper 6-2, and pivot pin 9 contacts with first slipper, and the gap of placing brake disc 2 is arranged between two slipper.

The utility model casts out the installation site of bearing 8 and pin hole 11 on original caliper 5, during use, be installed on two rear wheel hubs 1 of car through tong holder 3, wheel hub 1, brake disc 2 is that one and tong holder 3 form turning unit, brake disc 2 places between the first slipper 6-1 and the second slipper 6-2, when needing braking during standstill, at the handle in vehicle handle, handle, at its lower end is through backguy pulling pull bar 7, pull bar 7 is a fulcrum with bearing 8, pull bar 7 other ends promote pivot pin 9 slip 0.6mm in pin hole 11, pivot pin 9 other ends directly promote the first slipper 6-1, because pivot pin 9 slides in caliper 5 and is suspended on the support 4, when promoting the first slipper 6-1, caliper 5 produces antagonistic force and hooks the second slipper 6-2 counter motion 0.3mm, reach two slipper and respectively walk 0.3mm to the centre, embrace brake disc 2, reach the purpose of braking, when unclamping the car inner handle, pivot pin 9 is by spring 10 returns, the first slipper 6-1 and the second slipper 6-2 pressure are removed, brake disc 2 rotations when garage is walked, swirling eddy is separated two each 0.3mm of slipper, and vehicle is normally rotated, the utility model acts on two trailing wheels simultaneously, good braking effect, manufacturing process is simple, overall weight is light, has alleviated the energy-output ratio of car, being suitable for most electrocar, is the innovation on the Parking Brake.
