Mechanism for regulating height and angle of vehicle steering column assembly

The utility model discloses steering mast assembly of a height and angular adjustment mechanism for car, which comprises a subframe, an upper support, an upper column casing, a lower column casing, a steering upper spindle, an angular adjusting yoke, an axial adjusting yoke, an adjusting handle and an adjusting handle stem. The upper support and subframe are installed separately in the upper column casing and the lower column casing, fixed to the car body. The angular adjusting yoke is welded on the upper support and the axial adjusting yoke, positioned by the inner side of the angular adjusting yoke, is welded to the upper column casing. There is provided an arc-shaped groove on the angular adjusting yoke and an axial groove on the axial adjusting yoke. The adjusting handle stem passes through the point of intersection of the two grooves and is connected with the adjusting handle on the outside end. The realization of the height and angular adjustment of this governor mechanism mainly depends on the axial slippage of between the axial adjusting yoke, angular adjusting yoke, and the upper and lower column casings. The steering wheel can be adjusted to a huge extent, thereby drivers in different shapes can all find the most comfortable position to drive in through the height and angular adjustment of the steering mast.
