Abstract
The utility model discloses an automobile starting safety device, in particular to an antiskid device for manual automobile starting at slope section. The automobile starting safety device comprises a gearbox and an input shaft, an overrunning clutch is installed on the input shaft. In order to better realize the purpose of the utility model, the overrunning clutch is a roller overrunning clutch. The roller overrunning clutch is arranged on the same section of the input shaft radial, at least two rollers are symmetrically or uniformly arranged on the periphery of the input shaft. Adopting the structural device of the utility model can effectively protect the safety starting of manual automobile, and the structure is simple, no need to change parts or structure of the automobile transmission device, so be unable to affect the existent strength and function of the automobile, etc.
Description
Technical field:
The utility model relates to a kind of automobile starting safety installations, and the anti-skidding luggage when particularly being suitable for manual automobile and starting in gradient location is put.
Background technique:
When automobile going up a slope starting and when on the slope, moveing backward, if the also not contact of engine misses or clutch takes place the mismate of clutch and brake, automobile is because the effect of gravity to sloping slid underneath with slide, causes traffic accident.Therefore the fully-automatic gearbox automobile has anti-slip function because its hydraulic power speed change driver carries free wheel device at present.And all do not install on the manual automobile corresponding device thereof and structure prevent automobile at this moment slip and slide, be the clean boot that guarantees automobile by driver's technical merit and operating experience.Up to the present, automobile industry does not consider that all the free wheel device that hydraulic power speed change driver is carried separates separately the non-slip safety device as manual-gear vehicle.
28-90 page or leaf to 28-94 page or leaf has been introduced multiple free wheel device in " mechanical engineering manual " the 5th volume of nineteen eighty-two China Machine Press's publication.
The model utility content:
The purpose of this utility model is to provide a kind of principle of free wheel device of utilizing to reach the device of manual automobile in the hillside fields clean boot.Above-mentioned purpose is achieved in that
A kind of automobile starting safety installations comprises gearbox and input shaft, and free wheel device is installed on input shaft.
For realizing the purpose of this utility model better, free wheel device is a roller overrunning clutch.Roller surmounts device on the radially same cross section of input shaft, has two rollers and symmetry at least or is distributed on the input shaft peripheral position.
Adopt constructional device of the present utility model, protective action is effectively played in the clean boot of energy adversary gear automobile, and simple in structure, and therefore the part, the structure that do not need to change automotive trannsmission system can not influence existing intensity of automobile and performance etc.
Description of drawings:
Fig. 1 is an automobile starting safety installations assembling schematic representation;
Fig. 2 is the A-A generalized section among Fig. 1;
Fig. 3 is the fundamental diagram of roller overrunning clutch.
Embodiment:
As Fig. 1, Fig. 2, shown in Figure 3, the automobile starting safety installations comprises gearbox and input shaft 1, and free wheel device 2 is installed on input shaft 1.
The outer shroud of free wheel device 2 can be directly installed in the mating hole on the gear box 3.
As shown in Figure 3, roller overrunning clutch comprises the spring of roller 6, outer shroud 7, restriction roller 6.Roller 6 is arranged in the groove on the outer shroud 7.
Embodiment:
As shown in fig. 1, at the input shaft 1 of automobile gearbox free wheel device 2 has been installed.As shown in Figure 2, what free wheel device 2 adopted is roller overrunning clutch, with the star-wheel of input shaft 1 as free wheel device, the periphery of the outer shroud 7 of roller overrunning clutch is designed to polygonal, and be embedded on the support body 5 in the corresponding polygonal hole, guarantee that outer shroud 7 is fixing with input shaft 1 rotation, can certainly adopt other modes such as structures such as locating stud, positioning block to reach the purpose that restriction outer shroud 7 rotates.At the end face of roller overrunning clutch with spacing as free wheel device axial displacement of plate washer 4 or other technique known method.Support body 5 is installed on the casing 3 of gearbox.For when free wheel device 2 blocks input shaft 1, input shaft 1 stressed evenly, free wheel device 2 should be provided with more than two and symmetry or be distributed in the radially peripheral position in same cross section of input shaft 1.
As shown in Figure 3; when automobile normal running; input shaft 1 turns clockwise; 2 pairs of input shafts 1 of free wheel device do not provide constraints; and when automobile is in the hillside fields and start or move backward above the slope; if the clutch of vehicle transmission is contact or engine misses not; because the effect automobile of gravity can and slide to lower slider; input shaft 1 is rotated counterclockwise thereupon; the working principle of roller overrunning clutch is exactly to utilize the groove and the relation of the angle between the input shaft 1 of outer shroud 7, and roller 6 blocks input shaft 1, reaches the purpose that stops input shaft 1 counter-rotating; thereby prevent the above-mentioned slip of automobile or slide, play the effect of safety protection.
In the application process of reality, can certainly adopt the free wheel device of other structure to replace roller overrunning clutch in the foregoing description, and structurally do corresponding change, equally also can realize the purpose of this utility model.
When being installed in free wheel device 2 on the input shaft 1, modes such as the support body 5 that the outer shroud 7 of free wheel device 2 is installed can also connect by bolt, rivet welding connection are fixed on other position of the casing 3 or the automobile of gearbox.Can certainly design at gearbox, take into full account in the course of working, the structure of its support body 5 is set directly on the gear box 3, the outer shroud 7 of free wheel device 2 is installed in the corresponding mating hole on the gear box 3, makes structure compact more.
