Description
Technical field
The utility model belongs to vehicle brake technology field, and in particular to a kind of heavy truck with centre brake is stayed
Vehicle braking system.
Background technique
The parking braking system of current commerial vehicle, what parking brake was widely used is the mode of wheel braking, is passed through
Composite braking gas chamber is matched on the brake, achievees the purpose that parking braking using the spring-force driven dual of spring cylinder.Due to compound
Brake chamber shape is larger, and composite braking gas chamber occupied space at wheel is larger, when vehicle suspension uses independent suspension structure
When do not have arrangement space, influence suspension system performance.It is therefore desirable to be under the premise of guaranteeing parking braking system performance
The arrangement of suspension system provides enough spaces.
Utility model content
(1) technical problems to be solved
The utility model proposes a kind of heavy truck parking braking system with centre brake, to solve how to optimize
The technical issues of performance of parking brake, reduction braking system space.
(2) technical solution
In order to solve the above-mentioned technical problem, the heavy truck parking system with centre brake that the utility model proposes a kind of
Dynamic system, which uses generator pressure control method, by spring brake chamber, centre brake, brake disc and braking
Device hold-down support composition；Wherein, centre brake is mounted on the brake hold-down support on transfer case；Spring brake chamber peace
On centre brake；Brake disc is mounted on the flange of transfer case output end；After spring brake chamber inflation, center system
Dynamic device is separated with brake disc, releases braking；After spring brake chamber exhaust, centre brake implements system in conjunction with brake disc
It is dynamic.
Further, centre brake is mounted on two bridge output end of transfer case.
Further, the brake force of centre brake is 17792N, and the diameter of brake disc is 400mm.
(3) beneficial effect
The utility model proposes the heavy truck parking braking system with centre brake, by spring brake chamber,
Centre brake, brake disc and brake hold-down support composition.Wherein, it is solid to be mounted on the brake on transfer case for centre brake
Determine on support, spring brake chamber is mounted on centre brake, and brake disc is mounted on the flange of transfer case output end.This reality
With novel by matching centre brake, in light-weighted while making the space at front axle wheel side bigger, front axle suspension arrangement
Space structure and performance advanced optimize.Centre brake is located in the power train after speed changer, for braking speed changer
Second axis or transmission shaft, required braking moment is smaller, and is not take up the space on wheel side.
Detailed description of the invention
Fig. 1 is the utility model embodiment heavy truck parking braking system schematic diagram.
Specific embodiment
It is with reference to the accompanying drawings and examples, practical to this to keep the purpose of this utility model, content and advantage clearer
Novel specific embodiment is described in further detail.
The present embodiment proposes a kind of heavy truck parking braking system with centre brake, and structure is as shown in Figure 1.
The parking braking system uses generator pressure control method, is consolidated by spring brake chamber 1, centre brake 2, brake disc 3 and brake
Determine the composition of support 4.Wherein, centre brake 2 is mounted on the brake hold-down support 4 on transfer case, and spring brake chamber 1 is pacified
On centre brake 2；Brake disc 3 is mounted on the flange of transfer case output end.In use, being filled in spring brake chamber 1
After gas, centre brake 2 is separated with brake disc 3, releases braking；In spring brake chamber 1 after exhaust, centre brake 2 and system
Moving plate 3 combines, and implements braking, releases stress about 4.13bar.
In the present embodiment, according to whole-car parameters table data, analyzed through space layout inspection and relevant calculation, by center brake
Device is mounted on two bridge output end of transfer case.
Brake force calculates:
In 40% ramp climb and fall, vehicle sliding force is 115136N, and the braking moment needed is 70117.8Nm, wheel
The brake force that side brake is capable of providing is 85207N, and the braking moment being capable of providing is 51891.4Nm, it is still necessary to the system of offer
Kinetic moment is at least 18226.4Nm, and the speed ratio of bridge is 5.921, then centre brake is needed to provide at least braking of 3078.26Nm
Torque.

| Mass center is away from the first front axle centre linear distance | mm | 3857 |
| Radius of wheel | mm | 598 |
According to the braking moment calculation formula of centre brake:
Braking moment=centre brake brake force × brake disc radius
In view of limiting factors such as arrangement spaces, according to the data related data of centre brake brake force, selection center
Brake braking force is 17792N, needs the diameter of centre brake brake disc for 396.8mm, about 15.6 inches.
By the above analytical calculation and arrangement space inspection, the center that the present embodiment final choice brake force is 17792N is made
The brake disc that dynamic device and diameter are 400mm.
Using above-mentioned braking system, the gradient in slope of going up a slope can reach 57%, and the descending gradient in slope can reach 42%, be higher than whole
The index request of the vehicle parking gradient 40%.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
