Description

[Detailed Description of the Invention] The present invention relates to an improvement in the cab suspension of an automobile.

Conventionally, a cab-side bracket provided at the front end of the cab, a frame-side bracket provided at the front end of the chassis frame, and the front end was pivoted to the frame-side bracket and the rear end to the cab-side bracket, respectively. A cab suspension is known that has a suspension arm and a support mechanism equipped with a coil spring contracted between the cab side bracket and the suspension arm on the left and right sides of the vehicle, respectively. In such a cab suspension, an anti-roll bar is provided between the left and right suspension arms to reduce the large tilt of the cab to the left and right when the vehicle turns, etc., and an anti-roll bar is provided between the suspension arms and the suspension arm to damp the displacement of the coil spring. It is necessary to install a shock absorber between the cabs.

The present invention provides a suspension having such an anti-roll bar and shock absorber,
The object of the present invention is to provide a cab suspension that is compact with a small number of parts and has excellent maintainability in which the shock absorber can be easily attached and detached.

The present invention consists of a cab-side bracket provided at the front end of the cab, a frame-side bracket provided at the front end of the chassis frame, the front end being pivoted to the frame bracket, and the rear end being pivoted to the cab-side bracket. In a vehicle having a suspension arm and a support mechanism having a coil spring compressed between the cab side bracket and the suspension arm on the left and right sides of the vehicle, each of the left and right support mechanisms an extension part formed on the suspension arm and extending forward from the shaft attachment part with the frame side bracket; It has an anti-roll bar located approximately on the axis of the shaft attachment portion of the suspension arm and the frame-side bracket, and a shock absorber whose upper end is supported by the cab and whose lower end is supported by the end of the roll bar. This article focuses on the cab suspension of an automobile, which is characterized by the following.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, numeral 2 is the cab of the automobile, 4 is the chassis frame, 6 is the cab frame forming the skeleton of the cab 2, 8 is the cab-side bracket fixed to the front end of the cab frame, and 10 is the front end of the chassis frame 4. frame side bracket fixed to 12
18 is a suspension arm whose front end is pivoted to the bracket 10 by a pin 14 and its rear end to the bracket 8 by a pin 16, and 18 is compressed between the suspension arm and the bracket 8. Support mechanisms comprising coil springs are provided on the left and right sides of the vehicle, respectively. 20 is a pin 14 formed on both arms 12, respectively.
22 is an anti-roll bar whose both ends are supported by the tips of both extension parts 20, and the axis of the central twisting part 22a is positioned approximately on the axis of the pin 14; 24 is a cab frame; A bracket 26 is fixed to the front end surface of the anti-roll bar 22, and a shock absorber 26 has an upper end supported by the bracket 24 and a lower end supported by the end of the anti-roll bar 22.

According to the above configuration, since the end of the anti-roll bar 22 supports the lower end of the shock absorber 26, the lower end is separately attached to the suspension arm 12.
This eliminates the need for parts to be attached to the system, making it possible to reduce the number of parts and make the entire system more compact. Also, the shock absorber 26 is connected to the coil spring 1.
Since the shock absorber 26 is located at the front end of the cab frame 6 away from the shock absorber 8, the shock absorber 26 can be easily attached and detached, and maintainability is excellent. Furthermore, since the shock absorber 26 is located away from the center of rotation of the suspension arm 12, the shock absorber 26
The stroke of 6 is the sum of the vertical displacement of the cab 2 and the vertical displacement of the tip of the extension 20 relative to the pin 14, and the operating stroke can be set large, thereby causing the shock absorber 26 to adjust to the vertical displacement of the cab 2. It can be made to work sensitively.
