Abstract

(57) [Summary] [Purpose] The base of the vehicle's steering wheel column is attached to a single frame, and the rotational support of the steering operation-related functional parts is concentrated on this frame, reducing the number of parts and improving assembly. We aim to make it easier. [Structure] The base of the vehicle's steering wheel column is mounted on one bracket, and the steering-related clutch, brake pedal rotation fulcrum, tilt handle rotation fulcrum, and parking brake lever rotation fulcrum are concentrated on this bracket. Established.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a mounting device for steering operation-related parts at the base of a steering wheel column of a passenger vehicle.

0002

[Conventional technology]

Clutches, brake pedal rotational fulcrums, and clutches used in conventional passenger vehicle operations The rotation fulcrum of the steering wheel and parking brake lever, etc. are They were spread out due to the nature of the vessels.

0003

[Problem that the idea aims to solve]

As mentioned above, when the flight control equipment is distributed, the number of parts is simply reduced. Not only do the numbers increase, but it also becomes impossible to assemble on an assembly subline, and it becomes impossible to assemble directly on the main assembly line. Because small parts are assembled at the factory, the main assembly line becomes longer and the number of assembly steps increases. Moreover, it became larger when assembled.

0004

[Means to solve the problem]

The present invention attaches the base of the vehicle's steering wheel column to one bracket, and Clutch related to steering operation, brake pedal rotation fulcrum, tilt handle The above-mentioned problem can be solved by providing a rotation fulcrum for the parking brake lever and a rotation fulcrum for the parking brake lever. Settled.

[0005]

[Effect]

The clutch pin on the left end of the rotating shaft that passes through the bracket at the base of the vehicle's steering column. When you step on the lever with your left foot, the vehicle's main clutch is disengaged and the engine is turned off. Power to the transmission is cut off, and when you take your foot off, the force of the return spring Then, the clutch becomes engaged again. Also, the brake pedal on the right end of the rotation axis is on the left. The right brake operates separately, and when the left pedal is pressed, only the left brake is braked, causing the vehicle to turn left and turn the right brake. When the pedal is depressed, only the right brake is applied and the vehicle turns to the right. Diagonal of the rotation axis A pivot pin that supports the tilt handle column fits into the rear boss, and the tilt handle column By switching the positioning groove using the tilt lever below the dollar column, the The angle of inclination of the handle column can be adjusted using the movable pin as an axis. More bra There is a parking brake lever fulcrum boss below the bracket, and both left and right brake pedals Connect the parking brake to the protrusion on the arm of the brake pedal while pressing down at the same time. By latching the lever, it is possible to park even on slopes. these maneuvers The structure is simplified by concentrating the functional parts related to operation in one frame. This also makes assembly easier.

【Example】

An embodiment of the present invention will be described with reference to the drawings. The bracket 2 for attaching the clutch is formed into a U-shape in plan view, and the clutch holder is Attach it to the upper surface of the housing, and pass one pipe 3 through the upper rear side of the bracket 2. A clutch pedal 5 is attached to the left side of the rotating shaft 4 fitted to the inner diameter of the pipe 3. Loosely fit the boss, fix the boss of the left brake pedal 6 on the right end, and then attach the boss of the left brake pedal 6 to the right end. Boss 7 fits loosely into rotation shaft 4 to form a pendant-type clutch and brake pedal. are doing.

[0007] The clutch pedal 5 and brake pedals 6 and 7 are each operated by links, levers, etc. Latch, connected to the functional parts of the left and right brakes, and the clutch pedal at the left end of the rotation axis 4 5 with your left foot, the vehicle's main clutch is disengaged and the engine is turned off. Power to the transmission is cut off, and when you take your foot off, the force of the return spring Then, the clutch becomes engaged again. Also, the brake pedal 6 on the right end of the rotation axis 4 , 7 operate separately for the left and right brakes, and when the left brake pedal 6 is depressed, only the left brake is braked. The vehicle turns to the left, and when the right brake pedal 7 is pressed, only the right brake is applied and the vehicle stops. Turn right.

[0008] Bosses 8a, 8a are fixed through and through diagonally rearward of the rotating shaft 4 of the bracket 2, and into the hole and boss 1b of the upward U-shaped mounting plate 1a attached to the lower part of the handle column 1. , insert the fulcrum pin 8 and tighten it with the nut 8b, and the two circumferential grooves of the fulcrum pin 8 are , O-rings 12, 12 are interposed, so the handle column 1 is elastically supported. This prevents vibrations from the engine and main body from being transmitted to the handle. In addition, it serves as a braking action when adjusting the steering wheel angle. Also, handle column 1 When the lower tilt lever 9 is tilted downward, the front and rear direction fixed to the base of the lever 9 is tilted downward. The engagement arm 9a, which is wedge-shaped when viewed from above, escapes from the groove of the groove fitting 15, so After tilting the steering column 1 back and forth around the fulcrum pin 8, turn the tilt lever. 9 is released, the tilt lever 9 is rotated back by the return spring and the engagement arm 9 is rotated. a is fitted into another groove of the groove fitting 15 and positioned, and eventually the fulcrum pin 8 is used as the axis. The angle of inclination of steering wheel column 1 will be set to the optimum angle to match the physique and posture of the driver. It can be adjusted as desired. Note that the groove fitting 15 having the positioning groove is located at the front side. It has an L-shape when viewed from the side and is welded to the bottom surface of the mounting plate 1a, so the handle Even if the operating load becomes excessive, it will not deform and will not disengage from the groove.

[0009] Also, the fulcrum boss of the parking brake lever 10 is welded to the bottom of the bracket 2. With both left and right brake pedals 6 and 7 connected and depressed at the same time, press the left brake pedal. The latch 1 of the parking brake lever 10 is attached to the protrusion protruding from the arm of the parking brake pedal 6. By multiplying by 1, you can park even on slopes. To release, pull the lever from the protrusion. By removing the switch, the return spring works and returns to the original state.

0010 Furthermore, a receiver 16a installed on the upper part of the bracket 2 has an engine control The lever 16 is installed, and the constant speed traveling control lever 17 of the hydrostatic drive transmission The stopper 18 and the like of the above-mentioned control operation functional parts are also attached to the bracket 2. 1 3 is a constant speed running pedal.

[0011] A block where the fulcrum bosses, stoppers, etc. of the above-mentioned control operation functional parts are arranged centrally. Racket 2 has a U-shaped sheet metal structure with a bottom plate. By connecting the keys with the pipe 3 for the pivot point of the key pedal, it becomes a box structure and increases the rigidity. It gets expensive. As mentioned above, the control operation functional parts are assembled together on the assembly subline, By assembling the bottom plate of bracket 2 to the main body on the assembly line as a unit, This allows the main assembly line to be shortened and the number of man-hours to be reduced. 20 is bracket 2 The steering unit 21 housed inside and attached to the lower part of the steering column 1 is It's an orbit roll.

0012

[Effect of the idea]

The present invention attaches the base of the steering wheel column 1 of the vehicle to one bracket 2, and Bracket 2 includes a clutch related to steering operation, a pivot point for the brake pedal, and a tilt point. By arranging the rotation fulcrum of the steering wheel and the rotation fulcrum of the parking brake lever 10, The number of parts is reduced and the structure is simplified, allowing partial assembly on the assembly subline. This allows the main assembly line to be shortened, and the entire assembly to be made more compact. be able to.
