Abstract
The utility model relates to a parking braking driving mechanism for an agricultural transport vehicle. The parking braking driving mechanism for an agricultural transport vehicle comprises an anterior wire rope assembly and a middle rocker arm which is hinged with a vehicle frame. A pulley assembly is hinged between the anterior part and a hinged shaft, one end of a left and a right rear wire ropes is fixed with braking rocker arms of a left and a right brake, and the other end is connected by a connecting rack and is wound in a pulley groove. During braking time, the anterior wire rope is pulled, the pulling force is transferred onto the brake by the middle rocker arm and the rear wire rope, so the allocated braking force of the left and the right brakes is basically consistent. In addition, the transmission efficiency is improved, and the utility model is operated conveniently.
Description
The utility model relates to a kind of agriculture truck holding brake device, particularly relates to a kind of agriculture truck braking during standstill transmission device.
At present, agriculture truck braking during standstill transmission device comprises the brake-applying handle assembly that is fixed on the vehicle frame, the preceding steel rope that one end and brake-applying handle assembly are affixed, preceding steel rope sheath is fixed on the vehicle frame, the preceding steel rope other end connects intermediate rockers, left and right back steel rope one end connects the brake rocker arm in the left and right drg, and the other end connects intermediate rockers; The brake disc of right steel rope sheath one end and drg is connected, and the other end and preceding steel rope are hinged.During work, preceding steel rope pulling intermediate rockers, intermediate rockers spurs left back steel rope, promotes right back steel rope sheath, makes pulling force become thrust.Therefore brake efficiency is low, and the power on the left side is big, and the power on the right is little, and the power that is delivered to left and right sides drg is inhomogeneous, has influenced the reliability of braking during standstill, in the time of on load-carrying or ramp, moves handle and relatively requires great effort.
The purpose of this utility model is that a kind of operation of design is light, transmission efficiency height, the stressed uniform agriculture truck braking during standstill transmission device of left and right drg.
For achieving the above object, the utility model comprises brake-applying handle assembly and an end and the affixed preceding steel rope of brake-applying handle assembly that is fixed on the vehicle frame, and preceding steel rope sheath is fixed on the vehicle frame; Also comprise drg and the back steel rope left and right sides sheath affixed with drg; Hinged intermediate rockers on the vehicle frame, intermediate rockers front end and preceding steel rope end joint connection, the affixed pull back spring of intermediate rockers tail end.Hinged pulley assembly between intermediate rockers front end and its hinge; About back steel rope one end be connected with brake rocker arm in the drg, the other end is by the link span connection and in pulley groove.
The utility model is owing to hinged pulley assembly between intermediate rockers front end and its hinge, and about the back steel rope connect by link span and in pulley groove, at glancing impact, be the pulling steel rope, the driving efficiency height, rear wheel brake suffered braking force in the left and right sides is even, operates light, safe and reliable.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the layout scheme drawing of this agriculture truck braking during standstill transmission device;
Fig. 2 is the structural representation of this agriculture truck braking during standstill transmission device.
In the embodiment that accompanying drawing provides, brake-applying handle assembly 1 usefulness bolt is fixed on the vehicle frame, torque arm 2 is connected with steel rope 3 front ends, sheath 4 two ends and vehicle frame are connected, intermediate rockers 6 is hinged with vehicle frame, intermediate rockers 6 front ends and preceding steel rope 3 rear ends are connected, the affixed pull back spring 5 of its tail end, hinged pulley assembly 7 between intermediate rockers front end and its hinge; The brake disc of one end of back steel rope sheath 9,12 and drg 13,14 is affixed, the other end and vehicle frame are affixed, the brake rocker arm of one end of back steel rope 10,11 and drg 13,14 is affixed, and the other end connects with link span 8, and in the pulley groove of pulley assembly 7.
Move torque arm 2 during work, steel rope 3 moves forward, pulling intermediate rockers 6, and intermediate rockers rotates counterclockwise around hinge, drives pulley assembly 7 reaches, thereby makes the brake rocker arm in back steel rope 10, the 11 pulling drgs 13,14, reaches the purpose of braking during standstill.Unclamp torque arm 2, total system is returned to initial position by pull back spring 5.
