Abstract
The utility model discloses an anti-back brake used on a three-wheeled automobile or an agricultural vehicle. A pawl shaft installation seat, a steel plate, a bottom plate of the steel plate, a steel plate clamp used for an upper pressure plate of the steel plate and a steel plate clamp nut are fixed on the bottom plate of the steel plate; one end of a pawl shaft is arranged in a vertical plate hole of the pawl shaft installation seat and is fixed with a nut, and the other end is welded with a pawl; the upper end of a pawl separating swing arm is provided with a tension spring and an operation steel wire; the pawl is clamped in a groove of an anti-back brake drum by the tension spring; the operation steel wire is connected at the operation position of a driver; the pawl separating swing arm, the pawl shaft and the pawl are connected together; a brake shoe installation bottom plate is fixed on an axle; the anti-back brake drum is arranged on an axle head; the pawl can rotate along the groove on the surface of the anti-back brake drum during normal forward driving, and the operating personnel can control the operation steel wire to separate the pawl from the groove of the anti-back brake drum during backward movement, so as to back the vehicle. When the vehicle is parked on the mountain road or the ramp, the pawl is clamped in the groove of the anti-back brake drum under the action of the tension spring, so as to prevent the vehicle form backing.
Description
Technical field
A kind of anti-back drg that is applied on three wheeled motor vehicle or the agri-vehicle.
Background technology
Three wheeled motor vehicle and agri-vehicle have vast market in China rural area, it is a kind of important tool that is widely used in agricultural production and rural area transportation, along with party and state helps the agriculture, rural areas and farmers building a New Socialist Countryside, the enforcement of a series of Huinong's policies such as town and country coordinated development, and China's low-speed cars had cheap, reliable in quality is durable, middle low velocity, characteristics such as medium and small tonnage, not only make it better adapt to peasant's income level, usage level reaches the requirement to transportation means, also better satisfied the needs of rural area various uses, thereby made it to have had huge market potential and current demand.At present, the drg that domestic three wheeled motor vehicle and agricultural Transport Machinery are used does not all have the anti-retrogression device, navigating mate labour intensity is bigger, the reliability of braking is not high, particularly in parking or starting-up process, cause traffic accident more, caused unnecessary property damage and personal casualty for the user of service in vast rural area owing to vehicle falls back reliably to park at three wheeled motor vehicle that travels on the rugged hill path and agri-vehicle.
Summary of the invention
The technical problems to be solved in the utility model is at deficiency of the prior art, and a kind of anti-back drg that uses with three wheeled motor vehicle and agricultural Transport Machinery that is applicable to is provided.
The utility model anti-back drg is achieved by following technical proposals: the anti-back drg is mainly installed base plate, anti-back brake wheel, axletree spindle nose, axis head nut, ratchet, pawl axis, back-moving spring, ratchet separation pivoted arm, manipulating wire, pawl axis mount pad, four on steel plate card nut, two on steel plate card, steel plate top board, steel plate, steel plate base plate, axletree etc. by brake shoe brake cheek and is formed.
The pawl axis mount pad of the utility model anti-back drg, steel plate is all used the steel plate base plate, the steel plate top board, the steel plate card, steel plate card nut is fixed on the axletree, one end of pawl axis is by the pawl axis mounting hole on the pawl axis mount pad riser and be fixed on nut on the riser of pawl axis mount pad, ratchet is welded on the other end of pawl axis, the lower end that ratchet separates pivoted arm has a square opening and combines with square body on the pawl axis, make ratchet separate pivoted arm, pawl axis, ratchet is connected into an integral body, ratchet separates pivoted arm can drive pawl axis, ratchet rotates in the pawl axis mounting hole, ratchet separates the interior dress of the aperture back-moving spring of pivoted arm upper end, the power that ratchet separation pivoted arm is subjected to forward makes ratchet be stuck in the groove of anti-back brake wheel all the time, in another hole of ratchet separation pivoted arm upper end manipulating wire is housed, manipulating wire is connected to the actuated position place of navigating mate, brake shoe brake cheek is installed base plate and is fixed on the base of axletree, locks on the axle head that the anti-back brake wheel is installed and with axis head nut.
Actuating force of the present utility model is from the operating personal of three wheeled motor vehicle and agri-vehicle machinery and the pulling force of back-moving spring, vehicle normally moves ahead and is not affected, ratchet can rotate along the slippage of anti-back brake wheel groove, when parking on hill path or ramp, vehicle ratchet is stuck in the groove of anti-back brake wheel all the time because ratchet separation pivoted arm is subjected to the application force of back-moving spring, vehicle can only be moved ahead can not be retreated, guaranteed vehicle reliably parking on hill path or ramp, when vehicle normally retreats, operating personal acts on actuating force on the manipulating wire, the rotation of ratchet separation pivoted arm drives the ratchet rotation simultaneously and separates with anti-back brake wheel groove, finish the normal fallback procedures of vehicle, after the operator removes actuating force, ratchet separates pivoted arm makes ratchet be returned to again in the anti-back brake wheel groove under the effect of back-moving spring power, so this brake equipment has the braking effect of anti-back.
Description of drawings
The following accompanying drawing of the utility model anti-back drg:
Fig. 1 is the utility model anti-back drg integral structure scheme drawing;
Fig. 2 is ratchet, pawl axis and the pawl axis mount pad mounting structure scheme drawing of the utility model anti-back drg.
Among the figure: 1, brake shoe brake cheek is installed base plate, and 2, the anti-back brake wheel, 3, the axletree spindle nose, 4, axis head nut, 5, ratchet, 6, pawl axis, 7, back-moving spring, 8, ratchet separates pivoted arm, 9, manipulating wire, 10, pawl axis mount pad, 11, steel plate card nut, 12, the steel plate card, 13, steel plate top board, 14, steel plate, 15, the steel plate base plate, 16, axletree.
The specific embodiment
Below in conjunction with accompanying drawing the utility model anti-back drg principle of work is further described.
As shown in Figure 1 and Figure 2, the utility model anti-back drg comprises that brake shoe brake cheek installation base plate (1), anti-back brake wheel (2), axletree spindle nose (3), axis head nut (4), ratchet (5), pawl axis (6), back-moving spring (7), ratchet separate pivoted arm (8), manipulating wire (9), pawl axis mount pad (10), steel plate card nut (11), steel plate card (12), steel plate top board (13), steel plate (14), steel plate base plate (15), axletree compositions such as (16).
When three wheeled motor vehicle or agri-vehicle machinery when normally advancing the process of travelling, ratchet (5) can rotate along the groove slippage of anti-back brake wheel (2), drive wheel and guarantee the cruising of vehicle in working direction, when three wheeled motor vehicle or agri-vehicle will fall back operation, operating personal is applied to actuating force on the manipulating wire (9), manipulating wire (9) pulling ratchet separation pivoted arm (8) rotation drives ratchet (5) rotation simultaneously and separates with the groove of anti-back brake wheel (2), vehicle is finished retreated operation normally, finish retreat operation normally after, the operator removes actuating force makes ratchet separation pivoted arm (8) that ratchet (5) is returned in the groove of anti-back brake wheel (2), when vehicle is parked on hill path or ramp or is started to walk, ratchet (5) is stuck in the groove of anti-back brake wheel (2), stops anti-back brake wheel (2) to drive wheel and travels backward to reach and prevent the purpose that falls back.
