Abstract
The utility model discloses a tractor front wheel service brake device. At present, the brake mechanism of the walking tractor transport unit or the walking type transport unit adopts an independent rear wheel brake mechanism, the brake force of the rear wheel brake mechanism is insufficient when the brake is implemented, the brake distance is lengthened, the brake effect is not ideal, and the safety requirement is difficult to meet. The utility model discloses install braking pincers support of braking wheel cylinder, braking pincers and fix on the drive wheel shaft bearing cap of tractor gearbox body, form a whole with tractor gearbox body. When the tractor needs braking during walking, the brake caliper can press the brake disc to reduce the speed of the rotating brake disc or finally stop the rotating brake disc, and finally reduce the speed of the rotating wheel or finally stop the rotating wheel, so that the purpose of braking is achieved. The utility model discloses arresting gear and rear wheel arresting gear have increased the sensitivity of braking together, have shortened the reaction time of braking, make the braking rapider, effective.
Description
Technical field
The utility model relates to a kind of trac. front-wheel service brake device, is specially adapted to the front-wheel service brake that walker tractor transports unit or reaches the hand-variable transport plane.
Background technology
At present, walker tractor transportation unit or hand-variable transport plane all are to adopt independent trailing wheel stop mechanism owing to receiving cost, limitation of the technology, stop mechanism; This trailing wheel stop mechanism is in the moment of implementing braking, although enough braking forces are arranged with two rear locks, because trailing wheel just carries the part of car load load; Cause the car load braking force not enough; The stopping distance lengthening, braking effect is undesirable, so the back wheel brake system has been difficult to satisfy safety requirements separately.To this problem, people have designed multi-form mechanism, in the hope of reaching the raising deceleration and stopping performance, the purpose of guarantee driving safety through long-term practice.The restriction of factors such as but these mechanisms are owing to receive complex structure, and manufacturing cost is high, and is poor for applicability, can realize batch manufacturing and few.Therefore; For increasing traveling security; Press for a kind of actv. front-wheel service brake mechanism, to increase the deceleration and stopping performance of walker tractor transportation unit or hand-variable transport plane, this also is a kind of requisite measure that improves walker tractor transportation unit or hand-variable transport plane technology.
Summary of the invention
The purpose of the utility model just provides a kind of trac. front-wheel service brake device; With overcome present walker tractor transportation unit or and the hand-variable transport plane have only the trailing wheel braking and lack the deficiency of front wheel brake; Provide a kind of simple in structure, deceleration and stopping performance reliable, handle light and flexible, cost is low, has the trac. front-wheel service brake mechanism of operability and extensive applicability; The realization front and back wheel is braked simultaneously, improves the travel safety of trac..
The foregoing invention purpose is realized by following technical proposals: a kind of trac. front-wheel service brake device; Comprise the gear box of tractor body; The live axle bearing cap shim that is fixed as one with gearbox body; By the live axle of change speed gear box transmission system drives, connect fixing comprising wheel hub and, on the live axle bearing cap shim, be fixed with brake-caliper support by the wheel that front tyre and steel ring are formed by live axle; Brake cylinder and brake clamp are installed on the brake-caliper support, and friction lining fixing on the brake clamp can be pressed to the brake disc that is fixed on the wheel hub.
Take the utility model of above-mentioned measure, the brake-caliper support that brake cylinder, brake clamp are installed is fixed on the live axle bearing cap shim of gear box of tractor body, forms an integral body with the gear box of tractor body.The live axle that the propulsive effort of gear box of tractor is passed stretches out in the middle of the live axle bearing cap shim, live axle connect and rotation synchronously comprise wheel hub, brake disc and wheel.When trac. needs glancing impact in walking; Brake clamp can compress brake disc once working, and the brake disc speed of rotation is reduced or finally stops, because the terminal of brake disc is a wheel; So finally be the wheel velocity of rotation is reduced or finally to stop, reaching the purpose of braking.The utility model brake equipment has increased the sensitieness of braking with the trailing wheel brake equipment, has shortened the reaction time of braking, makes braking more rapidly, effectively.The utility model has changed the connection mode of wheel hub and wheel, has increased the brake disc and the brake clamp that cooperatively interact, just makes that travel safety greatly improves.It is simple, with low cost, scientific and reasonable to implement the utility model technology, and effect is remarkable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the utility model trac. front-wheel service brake mechanism.
The specific embodiment:
Because the structural principle of trac. the right and left is the same, for more clearly describing the structure of the utility model, at this monolateral brake equipment is described.Fig. 1 is the structural representation of the utility model trac. front-wheel service brake mechanism; Brake clamp friction lining 1 is fixed on the brake clamp 2 shown in figure; Brake clamp 2, brake cylinder 3 are fixed on the brake-caliper support 4, and brake-caliper support 4 is fixed on the live axle bearing cap shim 6 of gear box of tractor body 5.Live axle 7 is equipped with wheel hub 8 as the transmitter of trac. drive torque at its end; Wheel hub 8 is provided with bolt hole near the inboard of gear box of tractor 5; Brake disc 9 just is installed in wheel hub 8 inboards with bolt 10; Wheel hub 8 outsides also are provided with bolt hole, and after tire and steel ring were assembled into wheel 11, wheel 11 usefulness thru-bolts 12 were installed in wheel hub 8 outsides.Adopt cone match to add flat key 13 between wheel hub 8 and the live axle 7 and connects, also be designed with bolt 14 at the outer face of live axle 7, employing compresses plain cushion 15 and is fixed on wheel hub 8 firmly on the live axle 7.
When trac. was walked, brake disc 9 rotated with front-wheel 11.Be fixed on brake cylinder 3 on the brake-caliper support 4 can control brake the action of pincers 2, two friction linings 1 on the brake clamp 2 are installed in brake clamp 2 both sides towards brake disc 9 driving surfaces respectively.When chaufeur is stepped on brake pedal; Promote the master cylinder piston of master brake cylinder through push rod; Make master cylinder inside brake liquid under certain pressure, flow into brake cylinder 3; The hydraulic action that the piston of front wheel brake wheel cylinder 3 is transported by oil pipe, two friction linings 1 that promote on the brake clamp 2 are pressed to brake disc 9 generation friction brakinges, and it just looks like to vise the plate in the rotation with pliers that action is got up.Like this, non-rotary brake clamp 2 is just to one of brake disc 9 effect of the rotating friction moment with wheel 11 switched in opposite.After brake disc passes to wheel 11 with this moment, owing between wheel 11 and road surface adhewsive action is arranged, wheel 11 road pavement effects one periphery power forward, the road surface is also acting on antagonistic force backward, i.e. a braking force to wheel 11 simultaneously.Force whole trac. to produce certain deceleration/decel.Braking force is bigger, and then the trac. deceleration/decel is also bigger.When decontroling brake pedal, two friction linings 1 on the brake clamp 2 reset, and friction moment and braking force disappear, and brake action stops at once.
