Abstract
The utility model discloses a kind of seperated balance-type calipers applied to electric vehicle, including wheel cylinder body, wheelcylinder piston, shoe brake, the wheel cylinder body is made of for split type structure left wheel cylinder body (1), right wheel cylinder body (2), and the wheelcylinder piston is made of left wheelcylinder piston (8), right wheelcylinder piston (15) and respectively corresponds in left and right wheel cylinder body；The left and right wheel cylinder body is connected by connection bolt, guide pin, and the left and right wheelcylinder piston is respectively corresponded to connect with the shoe brake for being located at left side, right side.The effect that the utility model can reach the bilateral return equilibrium of shoe brake after releasing braking, eliminate abnormal sound, unified appropriate clearance is provided for vehicle wheel rotation, and reduction drags torque, improves course continuation mileage；This wheel cylinder body adopts a split structure, and reduces former monoblock type wheel cylinder mould development difficulty, reduces bad product rate.To make to brake the stable reinforcement of clamp brake, service life also greatly prolongs, and improves the safety of driving.
Description
Technical field
The present invention relates to brakes, are specifically related to a kind of caliper of brake.
Background technique
Currently, the electric vehicle motor development impetus is good, the requirement with people to healthy living and environmental protection is continuously improved, electricity
Motor-car movement has become the mainstream developed instantly.A safe electric vehicle, brake are keys, and brake is total by main pump
At, tubing assembly, caliper (also known as cylinder assembly) etc. constitute.Wherein, single action structure caliper is movement in one direction, wheel cylinder body is
Monoblock type, brake reaction speed is slow, and for single wheelcylinder piston in wheel cylinder body side, wheelcylinder piston uses nonmagnetic full tree
Rouge or all-metal material, by the wheelcylinder piston first drive outside hung brake shoe plate brake disc push again with inboard brake shoe plate
Contact simultaneously clamps on brake disc and generates brake force and realize braking, and braking completes the return of rear brake shoe by auxiliary return
Shoe plate spring complete, to prevent the shoe brake of two sides from being fully engaged against, be engaged unevenness, lead to abnormal sound, brake disc change occur
Shape situation reduces brake speed simultaneously with brake force, affects the overall performance of brake, and insensitivity is deteriorated, drop
Low travel safety.
Summary of the invention
It is an object of the present invention to overcome the above mentioned deficiencies, and providing a kind of can make that insensitivity is good, shoe brake
The good seperated balance-type caliper of return.
The purpose of the present invention is realized by following technical solution: seperated balance-type caliper, including wheel cylinder body, wheel cylinder are living
Plug, shoe brake, the wheel cylinder body are made of for split type structure left wheel cylinder body, right wheel cylinder body, and the wheelcylinder piston is by a left side
Wheelcylinder piston, right wheelcylinder piston are constituted and are respectively corresponded in left wheel cylinder body, right wheel cylinder body；The left wheel cylinder body and right wheel cylinder
Body is connected by connection bolt, guide pin, and the left wheelcylinder piston connects with the shoe brake positioned at left side, right wheelcylinder piston and position
Shoe brake in right side connects, and left hydraulic circuit is equipped in the left wheel cylinder body and is connected with left wheelcylinder piston, on the right side
Right hydraulic circuit is equipped in wheel cylinder body to connect with right wheelcylinder piston.
After structure of the invention, when braking, does not need in axial direction to move, and left and right wheelcylinder piston is located at braking
The two sides of disk release the effect that can reach the bilateral return equilibrium of shoe brake after braking, eliminate abnormal sound in this case, are vehicle
Wheel rotation provides unified appropriate clearance, and reduces the course continuation mileage that can also be improved electric vehicle while dragging torque；This
Wheel cylinder body adopts a split structure and processing technology, and high-intensitive connection bolt and guide pin phase are used between left and right wheel cylinder body
Even, former monoblock type wheel cylinder mould development difficulty is reduced, reduces bad product rate (such as integral and internal stomata is more), improves its life
Produce efficiency.Clamp brake is moderately good, service life also greatly prolongs to making to brake, and improves the safety of driving.
Detailed description of the invention
The present invention is described in further detail with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the seperated balance-type caliper of the present invention.
Fig. 2 is the right side view of Fig. 1.
Fig. 3 is the partial sectional view of Fig. 1.
Specific embodiment
Referring to figs. 1 to Fig. 3 it is found that present invention applies particularly to the seperated balance-type caliper of electric vehicle, including wheel cylinder body,
Wheelcylinder piston, shoe brake 13, the wheel cylinder body are made of, described point for split type structure left wheel cylinder body 1, right wheel cylinder body 2
Pump piston is made of left wheelcylinder piston 8, right wheelcylinder piston 15 and respectively corresponds in left wheel cylinder body 1, right wheel cylinder body 2；It is described
Left wheel cylinder body 1 is connected with right wheel cylinder body 2 by connection bolt 7 (built-in), guide pin 11 (external), the left wheelcylinder piston 8 and position
Shoe brake in left side connects, right wheelcylinder piston 15 connects with the shoe brake for being located at right side, sets in the left wheel cylinder body 1
There is left hydraulic circuit 16 to connect with left wheelcylinder piston 8, right hydraulic circuit 17 and right wheelcylinder piston are equipped in the right wheel cylinder body 2
15 connect.So that shoe brake stress, return are uniformly ground, abnormal sound phenomenon occur without shoe brake is unilateral, increase
The service life of shoe brake.
Wherein, there is deflating valve 4 and deflating valve dust cap 3 on the left wheel cylinder body 1, it is living in left wheel cylinder body 1 and left wheel cylinder
Be respectively arranged with rectangular loop 9, dustband 10 between plug 8, right wheel cylinder body 2 and right wheelcylinder piston 15, left side, right side shoe brake it
Between connected by shoe plate spring 12.When brake piping, left and right hydraulic circuit pressure release, drive of the left and right wheelcylinder piston in rectangular loop
Lower return also drives the shoe brake return of arranged on left and right sides simultaneously.
