Problems solved by technology
As a result, there will be the following problems: the height difference between the front and rear bolts 04, 05 and the road surface will increase, and when the above-mentioned turning lateral force acts, the load acting on the rear side bolt 05 will be reduced due to the reasons described in the embodiment. When the load applied to the front bolt 04 is greater than the same diameter as the front and rear bolts 04 and 05, the durability of the rear bolt 05 subjected to a large load will decrease
[0006] As a result, there is also the following problem: the front side bolt 04 will deviate from the straight line A along the front and rear direction of the vehicle body to the outside in the vehicle width direction, and the rear side bolt 05 will deviate from the The straight line A along the front-rear direction of the vehicle body is shifted inward in the vehicle width direction. Therefore, due to the above-mentioned load F, a large moment with the above-mentioned shift amount acting as a moment arm acts on the coupling parts 02a, 02b of the knuckle main body 02, so It is necessary to take measures such as making the front and rear bolts 04 and 05 thicker, which will become the main cause of weight increase

Embodiment Construction
[0020] Below, according to Figure 1 to Figure 5 The first embodiment of the present invention will be described.
[0021] like Figure 1 ~ Figure 3 As shown, the double V-arm suspension device S includes a steering knuckle 13 supported on the vehicle body via an upper arm 11 and a lower arm 12 . The steering knuckle 13 is composed of a steering knuckle main body 14 made of light alloy forging and a lower arm support bracket 15 made of iron-based material connected to its lower part. The knuckle main body 14 includes: an axle support part 14a that supports the axle of the wheel W so that it can rotate freely; The outer end is pivotally supported on the upper end of the upper arm support portion 14b.
[0022] from Figure 4 It can be clearly seen that a pair of front and rear coupling parts 14c, 14d protrude downward from the lower front and rear ends of the axle support part 14a of the steering knuckle body 14, and an upwardly recessed concave part 14e is formed between th...

The present invention relates to a suspension device, including a knuckle, formed so that the front and rear of the lower arm supporting bracket are fastened by the front and rear bolts to a front and a rear fastening part provided in the lower part of the knuckle body; and a single lower arm, which width direction inner end is connected to a vehicle body, and width direction outer end is connected to the lower arm supporting bracket through a pivot support; the lower arm and a pivot supporting connection part of the lower arm supporting bracket are located in a straight line for connecting the front and the rear bolts when viewed vertically, and the straight line is in toein conventionally, and the toein angle is decreased when the load towards the vehicle body rear playing action to theknuckle. In this way, when the vehicle wheel passes through convex pavement or brakes, and the load rearward of the vehicle plays action on the knuckle, the moment of the load torsion knuckle will bereduced, so that the load on the bolt may be reduced and the durability may be improved.
Description
[0001] The present invention is a divisional application of the Chinese invention patent application whose application number is 200510053708.4, the application date is March 10, 2005, and the invention name is "suspension device". [0002] technical field [0003] The present invention relates to a suspension device comprising: a steering knuckle configured to connect the front and rear parts of a lower arm support bracket to a front coupling part and a rear coupling part through front and rear bolts, and the coupling part is provided on the steering wheel. the lower part of the joint main body; and the lower arm, the inner end in the vehicle width direction is connected to the vehicle body, and the outer end in the vehicle width direction is connected to the lower arm support bracket. [0004] Background technique [0005] Figure 7 as well as Figure 8 Represents a known suspension device, the steering knuckle 01 of which connects the lower arm support bracket 03 to the...
