Description

[Detailed description of the invention] The present invention relates to a mounting structure that allows vehicle height sensors of the same size to be assembled as they are extremely easily even if the vehicle type is different, and is particularly suitable for use in conjunction with a vehicle height adjustment device. It is. In recent years, vehicle height adjustment devices designed to keep the vehicle height constant regardless of the number of passengers or the amount of cargo have become popular, and devices with various structures have been announced. The most common type is one in which the vertical position of the wheel relative to the vehicle body is detected, and the wheel is raised and lowered via a suspension or the like so that the wheel reaches a preset position. In this case, it is necessary to install a vehicle height sensor between the wheel and the vehicle body as a means of detecting the elevation position of the wheel, but since there is a suspension between the wheel and the vehicle body, it is actually A vehicle height sensor will be installed between the suspension and the vehicle body.

However, if the vehicle type is different or the suspension type is different, the distance between the suspension and the vehicle body will also vary accordingly, so when using a vehicle height sensor with a single dimension, Connection fittings of different lengths had to be prepared each time, which resulted in high costs.

From this point of view, the present invention aims to provide a vehicle height sensor mounting structure that allows a vehicle height sensor of a single dimension to be easily assembled without any problems to vehicles with different distances between the suspension and the vehicle body. purpose.

The structure of the vehicle height sensor mounting structure of the present invention that achieves this purpose is comprised of a swinging link that moves up and down as the suspension expands and contracts, and is interposed between the suspension and the vehicle body to determine the position of the wheels. A positioning bracket that can be fixed at any position in the longitudinal direction of the swing link is slidably attached to the swing link, and an upper end of a vehicle height sensor that can detect the vertical position of the wheel with respect to the vehicle body is pivotally connected to the vehicle body. The vehicle height sensor is characterized in that a lower end portion thereof is pivotally connected to the positioning bracket.

Hereinafter, an embodiment of the vehicle height sensor mounting structure according to the present invention will be described in detail with reference to FIG. 1, which shows the schematic front shape thereof, and FIG. 2, which shows the left side shape thereof. A strut (suspension) 13 in which a shock absorbing spring 11 and a vibration damping damper 12 are coaxially assembled is connected at its upper end (not shown) to a vehicle body 14 and at its lower end pivotally connected to a knuckle arm 15. There is. This knuckle arm 15, to which a wheel (not shown) is connected, has one end (not shown) pinned to the other end of a lower arm (swing link) 16 rotatably pivoted to the vehicle body 14, and the wheel is connected to the vehicle body 14. The upper end of the vehicle height sensor 17 that detects the vertical position is the bracket 19.
It is pivotally connected to the vehicle body 14 via. The lower end of this vehicle height sensor 17 is pivotally connected to a positioning bracket 19 attached to a lower arm 16 having a horseshoe-shaped cross section. It can be fixed integrally with a bolt 20 and a nut 2 at any desired position.

Although the distance between the swing link and the vehicle body varies widely depending on the type of vehicle and suspension type, in this embodiment the positioning bracket 19 is connected to the lower arm 16.
Since the vehicle height sensor 17 can be slid to any position along the vehicle body 14 and the lower arm 16,
It is possible to install it in an inclined state corresponding to the distance between the Accordingly, as the number of occupants changes and the loaded weight changes, the height of the lower arm 16 above the ground changes, and the vehicle height sensor 17 detects the vertical position of the wheels relative to the vehicle body 14. In this embodiment, the positioning bracket 19 of the vehicle height sensor 17 is connected to the lower arm 16.
However, the positioning bracket 19 can be attached to any rocking rod that swings following the vertical movement of the suspension. Therefore, the shape of the positioning bracket 19 is as follows.
It is preferable to set it appropriately depending on the cross-sectional shape of this swing rod.

As described above, according to the vehicle height sensor mounting structure of the present invention, the lower end of the vehicle height sensor, whose upper end is pivotally attached to the vehicle body, slides against the swinging rod that moves up and down in accordance with the load fluctuations of the suspension. Since the sensor is pivoted to a positioning bracket that can be attached to the sensor, it is possible to install a single-dimensional vehicle height sensor as is even if the suspension type or car model changes, thereby reducing overall costs. It is possible.
