Ensure traffic safety.
The content of the invention
The purpose of this utility model is that solve the deficiencies in the prior art, there is provided a kind of vehicle secondary brake apparatus, in vehicle
Have been provided with increasing on the premise of a set of brake apparatus the two-stage brake of one group of auxiliary braking, to realize the reliable system of vehicle
It is dynamic, it is ensured that traffic safety.
The purpose of this utility model is achieved through the following technical solutions：
A kind of vehicle secondary brake apparatus, including be installed on vehicle traction main shaft brake disc, be installed on by support
Oil cylinder or cylinder between drive shaft and vehicle crossbeam, two wheel cylinders being relatively arranged in oil cylinder or cylinder, install respectively
Brake-shoe in two wheel cylinder front ends, the oil circuit of the oil cylinder or the gas circuit of cylinder and the total oil pump of the brake system of vehicle or total gas
Pump is connected by pipeline connection, two wheel cylinders with the oil circuit of oil cylinder or the gas circuit of cylinder, and the disk edge of the brake disc is arranged at two
Between individual brake-shoe, by the synchronous oil-feed or air inlet and oil return or discouraged of two wheel cylinders, two brake-shoes are promoted synchronously to push away
Enter to clamp brake disc or retreat take-off the brake disk.
Brake disc of the present utility model can be sleeved on vehicle traction main shaft.Brake disc can be also arranged on by connecting bolt
On vehicle traction main shaft, the vehicle traction main shaft is two-segment type main spindle, and end plate is welded with two terminations that main shaft connects,
At least four connecting holes are uniformly machined with end plate, brake disc is arranged between two end plates and is machined with and end plate connection hole pair
The mounting hole answered, connecting bolt pass through end plate connecting hole and brake disc mounting hole, and brake disc is consolidated and is installed in drive shaft.
The oil circuit of the oil cylinder or the gas circuit of cylinder are machined on cylinder body, and oil circuit or gas circuit both ends connect with two wheel cylinders respectively.It is described
The both sides of drive shaft, the oil circuit or gas of each oil cylinder are symmetricly set in built with the oil cylinder or cylinder of two wheel cylinders and brake-shoe
The gas circuit of cylinder passes through pipeline connection with the total oil pump of brake system of vehicle or total air pump.
Using the utility model, when driver steps on brake pedal, the total oil pump of brake and drive system for vehicle with tow or total air pump are promoted
Piston movement, and then pressure is produced in oil circuit or gas circuit, brake fluid or brake gas transfer the pressure to the brake of vehicle in itself
While car piece, also transfer the pressure to two wheel cylinders and promote piston, piston promotes brake-shoe inwardly to move, and makes brake-shoe and system
Moving plate rubs, and produces further brake force, is filled by the former brake gear of vehicle plus the utility model secondary braking
Put, two groups of brake apparatus act on simultaneously, realize the reliable braking to vehicle.
The utility model is simple and reliable for structure, only need to install a branch additional between the drive shaft of existing vehicle and crossbeam
Frame, oil cylinder of the present utility model or cylinder assembly is rack-mount, brake disc is arranged in drive shaft, not shadow
The original structure of sound vehicle, low manufacture cost, using effect are good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
