Description

The present disclosure relates to a steering support that is attached to a steering member of a vehicle and supports steering.

A vehicle is equipped with a steering member extending in the vehicle width direction, and the steering of the vehicle is supported by a steering support attached to the steering member. The steering feeling of the vehicle is considered to change depending on the rigidity of the steering member and the steering support. The steering feel is an index for evaluating the driver's feeling when operating the steering wheel.

The steering support described in Patent Literature 1 has a box-like structure and is welded along the entire circumference of the outer peripheral surface of the steering member. This improves the rigidity of the steering support and steering member. As a result, the vibration of the steering is suppressed and the steering feel is improved.

Here, quickness can be cited as one of the factors that determine the steering feeling. Quickness is an index that indicates how quickly a steering operation is reflected in the behavior of the vehicle. Although the steering support of Patent Literature 1 can suppress steering vibration, it is difficult to improve quickness.

In one aspect of the present disclosure, it is desirable to improve the quickness of the vehicle.

One aspect of the present disclosure is a steering support that is configured to be attached to a steering member that is a rod-shaped member that is mounted on a vehicle while extending in the vehicle width direction, the steering support comprising a base portion, a projecting portion, and a fastening portion. , one or two reinforcements. The base is configured to be joined to the outer peripheral surface of the steering member while expanding along the outer peripheral surface of the steering member. The protruding portion is a portion that protrudes from the base and has two side walls that are configured to face each other side by side in the vehicle width direction. The fastening portion is provided on each side wall and configured to be fastened to a steering column of a vehicle located below the steering support. The reinforcing portion reinforces the projecting portion. Here, one side in the vehicle width direction is defined as the right side, and the other side is defined as the left side. In addition, in the base, the portion on the right side of the side wall located on the right side is defined as the right side portion, and the portion on the left side of the side wall located on the left side is defined as the left side portion. The reinforcing portion corresponds to the right side wall or the left side wall, and is provided from the corresponding side wall to the side portion of the base on the side where the side wall is located to reinforce the side wall.

According to the above configuration, the reinforcing portion is provided over the side wall of the protrusion and the side portion of the base located on the side wall side, so that the protrusion is laterally reinforced. Therefore, the rigidity (hereinafter referred to as torsional rigidity) of the steering support against the vehicle width direction force applied from the steering column via the fastening portion of the protrusion is improved. Thereby, it is possible to suppress the steering support from being deformed or displaced when a force to twist the steering column is applied. Furthermore, since the base portion is joined to the outer peripheral surface of the steering member, the rigidity of the portion of the steering member where the steering support is attached and its periphery is improved. As a result, displacement and deformation of the steering support are suppressed while the vehicle is running, and as a result, the intermediate shaft moves efficiently in accordance with the steering operation, and quickness can be improved.

One aspect of the present disclosure may include a reinforcing portion corresponding to the right side wall and a reinforcing portion corresponding to the left side wall.
According to the above configuration, since the projecting portion is reinforced from both the left and right sides, the torsional rigidity of the steering support is further improved. Therefore, it is possible to further improve quickness.

One aspect of the present disclosure may further include a bottom portion that is joined to the underside of the reinforcing portion and that reinforces the reinforcing portion.
According to the above configuration, since the reinforcing portion is reinforced from below by the bottom portion, the reinforcing portion can further reinforce the projecting portion from the sides. Therefore, the torsional rigidity of the steering support is further improved, and quickness can be further improved.

In one aspect of the present disclosure, the bottom portion may be joined to the respective sidewall near the fastening portion.
According to the above configuration, it is possible to reinforce the portion of the projecting portion in the vicinity of the fastening portion by the bottom portion. Therefore, the torsional rigidity of the steering support is effectively improved, and quickness can be further improved.

In one aspect of the present disclosure, the reinforcing portion may have at least one step that protrudes upward.
According to the above configuration, the rigidity of the reinforcing portion against force in the vehicle width direction is improved. Therefore, the torsional rigidity of the steering support is further improved, and quickness can be further improved.

In one aspect of the present disclosure, the reinforcing portion may be provided from the vicinity of the fastening portion on the corresponding side wall to the side portion of the base on the side where the side wall is located.
According to the above configuration, the projecting portion can be better reinforced by the reinforcing portion. Therefore, the torsional rigidity of the steering support is further improved, and quickness can be further improved.

In one aspect of the present disclosure, the fastening portion may be a hole into which a bolt extending substantially in the vehicle width direction is inserted to fasten the steering column.
According to the above configuration, when a force to twist the steering column is applied, a force in the vehicle width direction is urged to act on the steering support. Therefore, by improving the torsional rigidity of the steering support, the force that twists the steering column can be dealt with satisfactorily. As a result, it is possible to effectively suppress the displacement of the intermediate shaft during running, thereby improving quickness.
