Description
Technical field
The invention belongs to the back axle field of underloading vehicle, be specifically related to a kind of self-propelled vehicle and electric motor car mechanical brake type back axle.
Background technology
At present, the brake system of self-propelled vehicle and battery-driven car is divided into propons brake portion and back axle brake portion, this two brake portion generally adopts the brake modes of brake facing friction wheel hub side, and two brake handles namely on handlebar connect propons brake portion and back axle brake portion respectively.During brake, brake handle makes the wheel hub on propons and back axle stop operating by wirerope driving brake sheet.Because the speed of self-propelled vehicle and battery-driven car is fast, weight is large.Usual vehicle rear occupies the main by weight of vehicle, has very large inertia, and the key of car brakeing is as can be seen here back axle brake portion.Back axle braking is divided into oil brake and mechanical braking by brake mode.Oil brake in the plunger shaft in the brake system of back axle, makes piston rod promotion brake shoe that the brake facing on brake shoe is expanded outwardly by the Hydraulic Station on vehicle body for hydraulic oil to brake wheel hub, thus reach the effect of back axle braking.Mechanical braking drives brake arm to rotate by wirerope (or pull bar), thus realize camshaft rotation, and camshaft makes brake shoe expand outwardly thus the brake facing on brake shoe is braked wheel hub.Oil brake needs independent external Hydraulic Station to the hydraulic brake system fuel feeding of back axle, and cost of manufacture is high.In hydraulic brake system, the frequent and maintenance trouble of leakage of oil, removes and installs trouble when changing brake facing after brake facing wearing and tearing.Mechanical braking does not need external Hydraulic Station, and without the need to considering Leakage, when changing brake facing, simple to operation.Therefore common underloading vehicle adopts mechanical braking usually.
Existing underloading vehicle rear axle brake system comprises axle drive shaft, rear bridge tube, shoe sole, brake shoe, steady brace, wheel hub, rear bridge tube welds with shoe sole, brake shoe and shoe sole removably connect, brake shoe is provided with brake facing, wheel hub and axle drive shaft are bolted, and brake facing is positioned at wheel hub.Usually on rear bridge tube, be welded with steel plate seat and steady brace seat, steel plate seat and steel spring are bolted, and rear bridge tube is connected by U-bolt with steel spring.Steel spring is near the end of headstock and vehicle frame sliding block joint, and the vehicle head end of steel spring can be slided in the chute on vehicle frame.Steel spring is near the end of vehicle tail end and vehicle frame and be sliding block joint, and the vehicle tail end of steel spring can slide in the chute on vehicle frame.Steady brace seat on one end of steady brace and rear bridge tube is by pinned connection, and the other end and the vehicle frame of steady brace also pass through pinned connection.Vehicle is when braking, and stretcher drives bracket arm motion, and bracket arm drives brake arm to rotate, and brake arm rotarily drives camshaft and rotates, and camshaft makes brake shoe expand outwardly, thus the brake facing on brake shoe is braked wheel hub.
When vehicle is fully loaded and unloaded, the friction force needed for brake is different.But the length of the brake arm of prior art is fixing, namely in brake process, the arm of force is constant.Vehicle is unloaded and the effective arm of force of at full load is all inconvenient, is inconvenient to use.Chaufeur is when the vehicle that long-duration driving is fully loaded, the dynamics that touches on the brake is larger, but when driving suddenly empty-car, due to the subconsciousness of people, driver empty-car touches on the brake and also can suddenly as during the fully loaded vehicle of driving touch on the brake, now just there will be vehicle suddenly to stop, producing extreme shock can there is safety misadventure.If chaufeur is when the vehicle of long-duration driving zero load, the dynamics that touches on the brake is less, but when driving suddenly fully loaded vehicle, due to the subconsciousness of people, driver is fully loaded with vehicle and touches on the brake and also gently to touch on the brake as during driving empty-car, now just there will be vehicle to stop incessantly, braking distance is long, the accidents such as vehicle rear-end collision may occur.
Because the individual difference of chaufeur in actual life, require to differ to comfort level during brake.Such as: Ms due to foot-operated dynamics less, compare effort when touching on the brake, particularly vehicle heavy duty time, vehicle brake, needs larger braking force.But the length of existing brake arm immobilizes, foot-operated dynamics can only be increased to increase braking force during brake in brake process.Different adjustment cannot be done for different clients.
Vehicle at full load, vehicle frame, because the gravity of goods is to pressing down, makes the vehicle tail end slippage backward of steel spring, and the vehicle head end slippage forward of steel spring, realizes the effect of damping, but is connected with steady brace due to rear bridge tube, stops back axle to move backward.Because steady brace and steady brace seat are hinged, therefore back axle and steady brace can relatively rotate.In the process that vehicle frame presses down, steady brace holds rear bridge tube, and slight twisting occurs rear bridge tube.Due to the bearing pin not conllinear at the axial line of the bearing pin at the vehicle frame end points place of the steady brace of existing underloading vehicle and handler end points (both the end points of bracket arm and the handler hinged place) place of bracket arm.When when vehicle frame presses down, the vehicle frame end points (both the end points of steady brace and vehicle frame hinged place) of steady brace moves downward, by the vehicle frame end points (point of steady brace and vehicle frame junction) of steady brace, the handler end points of bracket arm, four limits that the strong point (both steady brace and steady brace seat hinge-point) of brake arm run-on point (both brake arm be connected with bracket arm point) and steady brace is formed are distorted and are out of shape, the distance between the strong point of steady brace and brake arm run-on point is made to change (both, bridge tube twisted), the angle between brake arm and bracket arm is made to become large, effective arm of force of brake arm is shortened, thus affect the brake distance of vehicle, make brake apart from elongated, affect vehicle safety.
