An engine mount assembly for coupling an engine to an airframe. The engine mount assembly includes a torsion bar coupled between the engine and the airframe. The torsion bar has upper and lower tapered bosses. Upper and lower arm assemblies couple the engine to the torsion bar. Each arm assembly has an end bell crank with a tapered socket that is adapted to receive a respective tapered boss therein to secure the end bell cranks to the torsion bar such that the end bell cranks rotate with the torsion bar responsive to movements of the engine.

A spring for sun visors includes a torque application section that extends from a holding section and applies torque when a main section is rotating. The holding section has a flat section that receives torque from a shaft. The torque application section has a first spring piece extending from one end of the holding section and a second spring piece extending from the other end of the holding section and being bent so as to fold back. The first spring piece has a first tip section that includes overhanging sections that are narrower than the width of the holding section. The second spring piece has a second tip section that is arranged so as to overlap on the outside of the overhanging sections. The overhanging sections are provided in an area extending from the torque receiving section to the first tip section.

A stabilizer for a chassis of a vehicle, having a curved stabilizer body (2) that forms a torsion spring, with a pendulum support (5, 6) and with a connecting section (7, 8, 46, 48), the connecting section (7, 8, 46, 48) is made of a metal and connects the stabilizer body (2) to the pendulum support (5, 6). The connecting section (7, 8, 46, 48) and the stabilizer body (2) are connected to one another by a snap-in and/or latch joint. To reduce assembly effort and expense and, at the same time, to join the stabilizer body (2) to the pendulum support (5, 6) in a secure manner, the stabilizer (1) and the pendulum support (5, 6) are characterized in that the connecting section has an opening (22) in which a plastic bearing shell (11) is arranged for fitting of a joint ball (23) of the pendulum support (5, 6).

A stabilizer clamp for a vehicle stabilizer may include an inner region for receiving a vehicle stabilizer and at least two at least partially opposite end regions for closing the stabilizer clamp. A first of the at least two at least partially opposite end regions may have a connecting element, and a second of the at least two at least partially opposite end regions may have a connecting element receptacle for producing at least a form-fitting connection between the connecting element and the connecting element receptacle. The connecting element may be at least one rivet, and the at least one connecting element receptacle is at least one rivet hole, and the form-fitting connection that is produced is at least a riveted connection.

A torsion spring installation means for a vehicle sunroof, front frame and vehicle sunroof. The torsion spring may have spring coils, a first torsion arm and a second torsion arm. The torsion spring installation means has a recess, the recess being configured as a cavity having an opening, for the purpose of receiving the spring coils, and having a wall and a recess bottom; a receiving component, the receiving component having an opening part, in order to receive the first torsion arm; wherein a guide block is provided on a first wall face of the wall in a fixed manner, the guide block extending out from the first wall face in such a way that its size gradually diminishes. The present means provides convenience of installation and removal, ease of maintenance and replacement, effective prevention of water penetration, the ability to prevent jumping out and wobbling, an extended service life.

A torsion spring adjuster for a rolling shutter is provided. A support plate has a first flange with a hole. A wheel is rotatably mountable on the support plate. The wheel has: a drive recess shaped to engage an end of a torsion spring; a first set of recesses around a circumference of the wheel, the first set of recesses being a first lateral distance from a first end of the wheel; a second set of recesses around a circumference of the wheel, the second set of recesses being a second lateral distance from the first end of the wheel. When the wheel is mounted on the support plate the first lateral distance aligns the first set of recesses with the hole of the first flange of the support plate, and the second lateral distance aligns the second set of recess past the first flange of the support plate.

The invention relates to a composite shock absorber for a polycrystalline diamond compact bit, comprising a drilling tool body having a water inlet, an impact body having a water outlet and forming a shock absorption cavity, a disc spring group having an annular pressing sleeve, a cylindrical torsion bar spring which has an external thread and a spline, is connected to the drilling tool body through threads and extended into an impactor and connected thereto through the spline, and the annular pressing sleeve, wherein bit vibration impact force is transmitted therebetween through a torsion transmission joint, and a bearing group is arranged between the lower end surface of the annular pressing sleeve and an annular step of the impact body. The composite shock absorber can weaken damage of the slippage effect to polycrystalline diamond compact cutting teeth, absorb axial vibration from a drill stem and prolong the service life of the bit.
