Abstract
The utility model discloses a kind of variable cross-section friction plate lightweight brakes, including floor pan assembly, brake shoe iron band friction plate and return spring, the bottom of the floor pan assembly is provided with dust cover, the floor pan assembly two sides are symmetrically installed with brake shoe iron band friction plate by pin shaft, the brake shoe iron is with the shoes that friction plate includes on the inside of friction plate and friction plate, return spring is installed between the shoes, camshaft is provided between one end of the shoes, the camshaft penetrates through dust cover and connect with the adjustment arm of dust cover bottom.The utility model is according to the actual wear situation of friction plate, using a kind of new design method, and light-weighted mentality of designing is used among the design of brake, change brake shoe iron material, the related environmentally friendly policy requirements of response country, reduce casting components and use, which can not only reduce weight, prolong the service life, and friction plate can be made preferably to be bonded with brake drum, generate good brake efficiency.
Description
Technical field
The utility model belongs to field of automobile parts and components, specifically a kind of variable cross-section friction plate lightweight brake.
Background technique
Currently, domestic all light trucks, middle card, heavy truck vehicle front axle brake assembly are using casting shoes uniform thickness friction plate
Structure, structure brake friction disc wear in vehicle use process is uneven, intermediate quick abrasion occurs, and two lateral wearings are full
The case where, friction plate effectively uses thickness thin, and overall utilization rate is low, and casting shoes overall weight is big, and it is light to be unfavorable for vehicle
Quantify the demand of development.
Summary of the invention
The purpose of this utility model is to provide a kind of variable cross-section friction plate lightweight brake.
To achieve the above object, the utility model includes floor pan assembly, brake shoe iron band friction plate and return spring, spy
Sign is that the bottom of the floor pan assembly is provided with dust cover, and the floor pan assembly two sides are symmetrically installed with braking by pin shaft
Shoes band friction plate, the brake shoe iron is with the shoes that friction plate includes on the inside of friction plate and friction plate, between the shoes
Return spring is installed, camshaft is provided between one end of the shoes, the camshaft penetrates through dust cover and dust cover
The adjustment arm of bottom connects.
Preferably, the side of the adjustment arm is additionally provided with bracket.
Preferably, the friction plate is designed using variable cross-section, the lateral dimension at the friction plate both ends is different.
With the above arrangement, actual wear situation of the utility model according to friction plate, using a kind of new design method,
Using variable cross-section friction plate, enable friction plate uniform wear, promote material rate, friction plate service life can extend 25% with
On.And light-weighted mentality of designing is used among the design of brake, change brake shoe iron material, responds national correlative link
Policy requirements are protected, casting components is reduced and uses, which can not only reduce weight, prolong the service life, and can make
Friction plate is preferably bonded with brake drum, generates good brake efficiency.
Detailed description of the invention
The utility model is described further now in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model friction plate.
In figure: 1, floor pan assembly, 2, dust cover, 3, pin shaft, 4, brake shoe iron band friction plate, 41, friction plate, 42, shoes,
5, return spring, 6, camshaft, 7, adjustment arm, 8, bracket.
Specific embodiment
As shown in Figure 1, 2, the utility model includes floor pan assembly 1, brake shoe iron band friction plate 4 and return spring 5, spy
Sign is that the bottom of the floor pan assembly 1 is provided with dust cover 2, and 1 two sides of floor pan assembly are symmetrically installed with by pin shaft 3
Brake shoe iron band friction plate 4, shoes 42 of the brake shoe iron with friction plate 4 including 41 inside of friction plate 41 and friction plate,
Return spring 5 is installed between the shoes 42, camshaft 6 is provided between one end of the shoes 42, the camshaft 6 passes through
It is connect across dust cover 2 with the adjustment arm 7 of 2 bottom of dust cover.
Further, the side of the adjustment arm 7 is additionally provided with bracket 8.
Further, the friction plate 41 is designed using variable cross-section, and the lateral dimension at 41 both ends of friction plate is different.
With the above arrangement, when the utility model is used, the brake is fixed on knuckle or vehicle by connecting bolt
On axis, gas chamber assembly is on bracket 8, gas chamber input air pressure, and under braking air chamber push rod thrust, adjustment arm 7 passes through spline
Camshaft 6 is driven to rotate, cam applies motivator to brake-shoe by idler wheel, roller shaft, makes two brake-shoes around pin shaft 3 outside
It opens, is contacted with the brake drum of rotation, brake force is generated by friction, when stopping braking, under the action of return spring 5, system
Dynamic hoof is rotated around 42 axis of shoes to be resetted, and braking is released.
