Existing brake system of car can be divided into following several according to drive energy:
1) muscular energy brake system---the brake system using the human body of chaufeur as unique braking energy source.
2) dynamic brake system---the brake system completely by being undertaken braking by the air pressure of the power-conversion of driving engine or the potential energy of hydraulic type.
3) servo brake system---dual-purpose manpower and engine power carry out the brake system braked.
Along with the demand for development of automotive automation degree and traveling comfort, existing dilly and heavy-duty vehicle adopt power brake system substantially, especially heavy-duty automobile brake system, substantially be rely on Pneumatic braking system, but, no matter adopt muscular energy braking sytem, power brake system or servo braking system, all rely on friction between brake facing and brake drum or braking clamp to realize wheel braking in braking procedure, brake facing Long-Time Service easily generates heat later, cause brake failure, especially for heavy motor vehicle, need that when long-term descent run instant cooling is carried out to brake drum and ensure braking quality, although can brake sensitivity be ensured to a certain extent, but, brake facing is easily aging, cause brake failure, there is larger potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of heavy motor vehicle dedicated hydraulic brake equipment, by using Hydraulic Pump as drag devices, in braking procedure, by spragging gear and ring gear engagement, Hydraulic Pump operates under the effect of automobile driving axle, the resistance produced in Hydraulic Pump operation process is driven to slow down the rotation of automobile driving axle, reach the object of brake, installation controllable check valve supporting with Hydraulic Pump oil inlet simultaneously, by controllable check valve adjustment Hydraulic Pump oil-feed resistance, in brake process except gears meshing, wipe without hard grind between brake gear and heavy motor vehicle car body, avoid because the problem causing friction member to lose efficacy is wiped in hard grind, guarantee heavy motor vehicle safe in operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of heavy motor vehicle dedicated hydraulic brake equipment, comprise the adapter plate be arranged on car chassis, Hydraulic Pump, gear drive, Hydraulic Pump arrangement of clutch and control setup, described Hydraulic Pump and adapter plate upper surface hinged, and the axis being parallel of its axis and automobile driving axle, between described hydraulic pump driveshaft and automobile driving axle, gear drive is set, the Hydraulic Pump arrangement of clutch for driving Hydraulic Pump to rotate around itself and adapter plate hinged place is provided with between described Hydraulic Pump and adapter plate, described Hydraulic Pump oil inlet is provided with controllable check valve.
Described adapter plate upper surface is provided with bearing, described Hydraulic Pump shell by bearing pin and bearing hinged.
Described Hydraulic Pump arrangement of clutch is cylinder, and the hinged ear that the piston rod end of described cylinder and Hydraulic Pump shell are arranged is hinged, described cylinder tail end by means of bearing pin and hinged-support hinged.
Described hydraulic pump drive end is provided with ring gear, and described automobile driving axle is provided with driving gear, and described driving gear engages with ring gear.
Described controllable check valve is electromagnetic valve, and described solenoid control end is all connected with control setup with cylinder control end.
Described control setup is PLC module.
The beneficial effect adopting technique scheme to produce is: the rotation being slowed down automobile driving axle by use Hydraulic Pump as drag devices, for automobile driving axle provides the resistance contrary with its hand of rotation, and the oil-feed resistance of Hydraulic Pump is adjusted by controllable check valve, the size of adjustment brake weight, mechanical friction in brake process, belongs to flexible brake, cancels existing mechanical friction mode, avoid causing brake failure because friction member is aging, guarantee traffic safety.
