[産業上の利用分野]
本考案は車両の懸架装置に用いられるトルクロ
ツドに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a torque rod used in a vehicle suspension system.

される。[Prior Art] A torque rod as disclosed in, for example, Japanese Utility Model Application No. 51-73410 is attached to a tandem axle type suspension system of a vehicle, and external force in the longitudinal direction acting on the axle is transferred to the vehicle body side through the torque rod. I accept it. The main body of the torque rod has an E-shaped cross section, and has eyelets or shaft holes at both ends, one of which is connected to the vehicle body and the other to the axle.

6が連結される。 As shown in FIG. 3, a torque rod 6 is connected between the upper end of a bracket 5 provided on each axle supporting the front and rear wheels 4 and the vehicle frame 2, respectively.
A torque rod 6 is connected between the lower end of each bracket 5 and the bracket 3 projecting downward from the vehicle frame 2.

成したものが用いられる。 The pair of upper and lower torque rods 6 support the excessive torque reaction force that acts on the axle when the vehicle travels on rough roads or when the brakes are operated, and are lightweight and have a cross-sectional shape that can withstand compressive loads and tensile loads. Generally, steel pipes with eyelets joined to both ends by welding are used, but in the case of cast products, which are advantageous in terms of cost, pipes with an E-shaped cross section and eyelets integrally formed at both ends are used. It will be done.

る。 However, with tandem axle suspension systems, the mechanism is complex and there is not enough free space under the vehicle body, so when a driver wants to change a tire due to an unexpected burst accident, it is easy to use the hydraulic jack in the middle of the torque rod. If you try to push up the car body by applying it to (acting as a load), there is a risk of the torque rod breaking.
[考案が解決しようとする問題点]
そこで、本考案の目的は上述の問題に鑑み、油

状に形成したものである。[Means for solving the problem] In order to achieve the above object, the structure of the present invention is such that the torque rod has a pair of upper and lower flanges that are integrally connected by a web to form a substantially E-shaped cross section.
Each outer surface of the pair of flanges is formed to have an arcuate cross section projecting outward.

ない。[Function] Since both the upper and lower sides of the torque rod have an arcuate cross section that protrudes outward, if you apply a hydraulic jack, which generally has a flat upper end surface, to the lower surface of the torque rod to push up the vehicle body, the vehicle body will At the same time as the machine begins to tilt sideways, the torque rod slips and becomes detached from the hydraulic jack. Therefore, there is no risk that the torque rod will completely bear the weight of the vehicle body and break.

るが、鍛造によることもできる。[Embodiment of the invention] As shown in FIG. 1, the torque rod 6 is provided with eyes 8 at both ends, and as shown in FIG. 2, the middle portion of the torque rod 6 has a substantially E-shaped cross section. That is, the intermediate portions of the upper flange 12 and the lower flange 13 are integrally connected by the web 15. In the present invention, the cross-sectional shape of the torque rod 6 is approximately E-shaped over its entire length, and each outer surface of the pair of upper and lower flanges of the torque rod 6 is formed into an arcuate cross-section that projects outward. Specifically, in order to prevent the hydraulic jack from hitting the lower flange 13 stably, the lower surface 13a of the lower flange 13 of the torque rod 6 is formed to have an arcuate cross-section projecting downward. The upper surface 12a of the upper flange 12 also has a similar cross-sectional shape. In other words, by making the parts vertically symmetrical, machining becomes easier and incorrect assembly can be avoided. The torque rod 6 according to the present invention is generally manufactured by casting, which is advantageous in terms of cost, but it can also be manufactured by forging.

げ荷重を受けて損傷する恐れがない。 According to the present invention, the lower surface 13a of the lower flange 13
By forming the cross section into an arcuate shape that projects downward, even if the hydraulic jack is applied to the lower surface of the torque rod 6, if the vehicle body tilts slightly to the side before the vehicle body is completely pushed up, the hydraulic jack will stop. Slippage occurs at the engagement portion between the push-up surface and the bottom surface 13a, and the hydraulic jack is repelled sideways. As mentioned above, since the hydraulic jack cannot be applied to the torque rod 6 to push up the vehicle body, there is no risk that the torque rod will be damaged by excessive bending load.
[考案の効果]
本考案は上述のように、トルクロツド上フラン
ジと下フランジとの間がウエブにより結合された
いわゆる断面形状エ字形のものであるから、断面
積が小さく軽量で、軸方向荷重に対する挫掘強度
が高く、通常の曲げ荷重に対しても十分な強度を
備えている。[Effects of the invention] As mentioned above, the present invention has a so-called E-shaped cross section in which the torque rod upper flange and lower flange are connected by a web, so it has a small cross-sectional area and is lightweight, and is resistant to axial loads. It has high crushing strength and is strong enough to withstand normal bending loads.

ツドに対する油圧式ジヤツキの安定した係合が阻
止されるので、トルクロツドに油圧式ジヤツキを
当てても、車体が完全に押し上げられない内に油
圧式ジヤツキが外れ、トルクロツドが過大な曲げ
荷重を受けて折損する恐れがない。 By forming the lower surface of the lower flange of the torque rod into an arcuate cross-section that protrudes downward, stable engagement of the hydraulic jack with the torque rod is prevented, so even if the hydraulic jack is applied to the torque rod, the vehicle body will not be completely rotated. There is no risk that the hydraulic jack will come off before it is pushed up and the torque rod will receive excessive bending load and break.
トルクロツドの断面形状が上下対称であるの
で、車両に対する誤組付の恐れがなく、作業の能
率向上に役立つ。 Since the cross-sectional shape of the torque rod is vertically symmetrical, there is no risk of incorrect assembly to the vehicle, which helps improve work efficiency.
