Abstract
The utility model relates to a safety device for the parking of the automobile, which is most suitable for various automobiles running in the mountain area. The utility model takes a star-wheel type shifting fork type two-way overrunning clutch substituting for the existing automobile parking brake device, a star-wheel is fixed to the back wall of the shell of the transmission, the inner ring is connected with the automobile drive shaft by a spline shaft, two sets of rollers are arranged between the star-wheel and the inner ring, and the shifting fork controls the rollers between the star-wheel and the inner ring for achieving the goal of advancing movement, backing and parking brake of the automobile. The utility model has enough brake torque, the parking on the ramp in the mountain area is safe, and the automobile starting on the ramp only needs the coordinating of the action of the clutch and the accelerator as the same as the automobile starting on the flat.
Description
The present invention relates to a kind of improved motor vehicle parking brake, particularly a kind of can make the automobile slope starting time and power-transfer clutch, throttle carry out the holding brake device of cooperation automatically.Be suitable for the various vehicles that travel in the mountain area.
The lock torque of existing motor vehicle parking brake derives from friction force, and slope starting is operated by the people.When slope starting, need power-transfer clutch, throttle, Parking Brake, just the cooperation of the left and right sides bipod and the right hand.This not only difficult grasp of fresh driver, the driver's operation that is exactly certain experience gets up also to have in various degree toward the phenomenon that glides.
The purpose of this invention is to provide a kind of improved car brake, can carry out cooperation effectively automatically when making the automobile slope starting.
The object of the present invention is achieved like this; The out star wheel of the shifting fork type two-way overrun clutch of external star-wheel type is connected in the case of transmission rear wall, and interior ring and transmission main shaft rear end spline link.Shift fork and two groups of rollers of control roller are housed between out star wheel and the interior ring; One group is the roller (this roller does not allow reversing automobile) that automobile surmounts power-transfer clutch when advancing, another group makes power-transfer clutch surmount when being reversing automobile roller (this roller does not allow automobile to advance).The roller that power-transfer clutch surmounted when fork controls made reversing automobile when automobile advances, another group just in time makes power-transfer clutch be in to surmount state, and automobile can only advance, and can not retreat.Therefore the same with the level land cooperation that needs power-transfer clutch and throttle when slope starting.
The present invention is easy to use, and has enough lock torques.
Below with reference to accompanying drawing to inventing further detailed description.
Figure ［ 1 ］ is a fundamental diagram of the present invention.
Among the figure ［ 1 ］, out star wheel ［ 1 ］ is fixed on the case of transmission rear wall, and its inside is equipped with cushion block ［ 2 ］ and is had the key seat alive ［ 9 ］ of the pin ［ 8 ］ of living.Interior ring ［ 6 ］ connects with propeller-shaft mutually by castellated shaft ［ 7 ］.Arrow indication master also is the rotation direction of interior ring ［ 6 ］ to being the propeller-shaft of automobile when advancing.Shift fork ［ 4 ］ and two groups of rollers ［ 3 ］ and ［ 5 ］ are housed between out star wheel ［ 1 ］ and the interior ring ［ 6 ］.The effect of the mobile frictionally of roller ［ 3 ］ and ［ 5 ］ and by the control of shift fork ［ 4 ］.Shown in figure ［ 1 ］, shift fork ［ 4 ］ has three control positions: dotted line ［ I ］ position is to allow automobile to advance; Solid line position is the stopping brake position; Dotted line ［ II ］ is to allow the reversing automobile position.
Shift fork ［ 4 ］ is to allow automobile to overtake in dotted line ［ I ］ position.When automobile advances, when promptly the interior ring ［ 6 ］ that links by castellated shaft ［ 7 ］ and propeller-shaft rotates according to the direction of arrow indication, roller ［ 5 ］ is under the effect of friction force, wider part displacement between cushion block ［ 2 ］ and interior ring ［ 6 ］ is moving, out star wheel ［ 1 ］ and interior ring ［ 6 ］ is in surmounts state.And roller ［ 3 ］ is under the friction force effect, and the narrower region between cushion block ［ 2 ］ and interior ring ［ 6 ］ moves, and the wedging between makes out star wheel ［ 1 ］ and interior ring ［ 6 ］ be in bonding state.Yet shift fork ［ 4 ］ stops moving of roller ［ 3 ］, forces it to rest on the broad position of out star wheel ［ 1 ］ and interior ring ［ 6 ］, and promptly shift fork ［ 4 ］ forces roller ［ 3 ］ to be in to surmount state.So, roller ［ 3 ］ and ［ 5 ］ all are in and surmount state.So the interior ring ［ 6 ］ that links by castellated shaft ［ 7 ］ and propeller-shaft allows to rotate according to the direction of arrow indication.Just allow automobile to overtake.
Shift fork during slope starting ［ 4 ］ is in dotted line ［ I ］ position, and roller ［ 3 ］ is controlled by shift fork ［ 4 ］, can't the narrower region of wedging between out star wheel ［ 1 ］ and interior ring ［ 6 ］.Ring ［ 6 ］ rotates according to the arrow direction in allowing.Yet, interior ring ［ 6 ］ is as long as there is the opposite sense of some arrow indications to rotate, be that automobile has some reversing backward, the roller of not controlled by shift fork ［ 4 ］ ［ 5 ］ is under the friction force effect so, move to the narrower region of out star wheel ［ 1 ］ and interior ring ［ 6 ］, the wedging between, ring ［ 6 ］ rotates according to the opposite sense of arrow indication in stoping automatically, just stops automobile to be moveed backward backward.So it is the automobile that adopts this structure Parking Brake when slope starting, there is no need and the cooperating of Parking Brake, identical with the level land starting.
In addition, because enough lock torques that roller ［ 5 ］ wedging is produced between out star wheel ［ 1 ］ and interior ring ［ 6 ］ can automatically prevent the automobile band to hang the unsafe condition that occurs when power goes up a slope.
Shift fork ［ 4 ］ is to allow automobile to travel in dotted line ［ II ］ position backward.At this moment, shift fork ［ 4 ］ is only controlled roller ［ 5 ］, and interior ring ［ 6 ］ can only rotate according to arrow indication opposite sense.Only allow automobile to move backward backward, do not allow to overtake.Its principle and shift fork ［ 4 ］ are in full accord in the situation of dotted line ［ I ］ position.
Shift fork ［ 4 ］ is the parking of automobile braking mode putting into practice the position.When shift fork ［ 4 ］ during at solid line position, roller ［ 3 ］ and ［ 5 ］ are not all controlled by shift fork ［ 4 ］.The interior ring ［ 6 ］ that links with propeller-shaft is that automobile is to overtake the time according to the direction of arrow indication, roller ［ 3 ］ is under the friction force effect, narrower region between out star wheel ［ 1 ］ and interior ring ［ 6 ］ moves, the wedging between, and ring ［ 6 ］ rotates in stoping; When interior ring ［ 6 ］ is an automobile when travelling according to the opposite sense of arrow indication backward, roller ［ 5 ］ also wedging stops its rotation equally between out star wheel ［ 1 ］ and interior ring ［ 6 ］.So do not allow automobile to travel forward or backward this moment, is in the braking during standstill state.
The transmission device of shift fork ［ 4 ］ is a mechanical type, is to use manual manipulation.Structure is similar substantially with existing transmission device.But, the power that imposes on the hand lever diminishes, and its size reduces to some extent.
This Parking Brake adopts overdrive clutch device, and often is in and surmounts state.Resisting moment when surmounting in order to reduce must guarantee the working accuracy of part, and adjust the spring force of the pin ［ 8 ］ of living proper.Spring force, roller weight, the pin weight of living on the pin sense of motion of living component and be zero.Drag-torque control when guaranteeing to surmount is in 0.5kgm.
The present invention can do series of products, it is heavy to divide, in, light, miniature four kinds.
With medium-sized series is example, and its parameter is:
The distance at roller section and star-wheel center is 130mm.
The exterior angle, contact point place of star-wheel is 6 °.
Interior ring diameter 180mm.
Roller diameter ∮ 40 * 60, divides two groups by totally 8.
